POINT PAPER

SUBJECT: Multimode/Multiband Digital Radio

PURPOSE: Muiti-phased effort at developing a software reprogrammable radiosystem. The Speakeasy program is phase one of this multi-phased effort.

FACTS:

The Multimode/Muitiband Digital Radio is a program intended to developa new radio architecture. The new radio will consist of modules which may be-ombined onto a common bus in order to share information and processing:apab:ity. The design will be such that additional processing power will bepossible through the addition of additional modules, or by replacing existingmodules with newer more powerful ones. This is the basic concept of the openr'hrtecture whl,,h this program hopes to take advantage of and deveiop.

The open architecture, combined with software reprogrammablitv and-ontrol will result in a radio system which can be altered by simply modifyingsoftware while maintaining the existing hardware.

When completed. it is envisioned that the Multimode/Multiband radiowill consist :) a common bus which acts as an information and control path toa number of modules. These modules will be of the same design and act as"processing engines.' If additional processing power is needed additional'common) modules will be added to the existing bus. All platforms will sharethe common modules and software controlling those modules. logistlc costs4,ii te reduced because of the limited type of modules needed and technco3':an oc:ncentrate on the limited type of modules to make them more reliable an:etter :er::rmers.

A* -.e :to~ran ororesses. and we actuailv deveo*: naraware. -e nay

.earn that .z not an optimal size/cost/processing solution for all themodules to te exactly the same or to have one common bus. However. the bas:cintent of the program will remain - develop a radio which can be easilvnodified by changing !ts software, and whose processing power can be enhancedby the addition of processing modules.

POINT PAPER

SUBJECT: Multimode/Multiband Digital Radio Antenna System

PURPOSE: Development and formal technology demonstration of a comDact.extremely wideband antenna system

FACTS:

In this joint development program. this Center will be conductid tnedevelopment, prototype fabricat-ion and demonstnation of a new :omact.extremely wideband antenna system.

The major technical factors to be demonstrated by this program :nclude:

Extremely wide bandwidth: 2 M}z to 3 GHz.

Capable o simultaneously supporting up to four frequency agi1ewaveforms.

- Compact: Mounted on a small vehicle. Drastically reduced size andweight as compared ,with conventional antennas covering this freauenc range.

- More survivable as comnarec with existing antennas due to itssmaller profile.

. This program is one o. our )oont development efforts with Rome Labora-tory. The primary objective :s to allow both services to maximize commonalitvpotential within constrained resources. CECOM will be the lead organ:zat:onon this program and contract opportunities will orig:nate ircm this location.

. The program will be structured into two phases, starting with anexploratory development effort and conciuding with a prototype of a compactwideband antenna which will be demonstrated. Demonstration of the antennasystem is expected in mid FY93.

. A follow-on phase will result in the development of an antenna insupport of the Digital Radio program that could form the basis of the follow-on development programs to evolve the combat net radio of the BattlefieldInformation System of 2015.

POINT PAPER

SUBJECT: VEHICULAR CONFORMAL ANTENNAS

OBJECTIVE: An exploratory development and feasibilitydemonstration effort to provide an assessment of tacticalvehicles, radio systems (both high frequency (HF) and veryhigh frequency (VHF)), and conformal antennas for use in thetactical er ;ironm-Tnt. Conformal antennas are those which bytheir mechanical -onfiguration are an integral part of thevehicle. As an example the antenna could be the handrail, asin the case of a tracked vehicle, or part of the fender orcanopy support in the case of a wheeled vehicle. Thetechnical assessment would identify candidate structures,candidate vehicles (i.e. HMMV, M1, M2), and candidate radiosystems followed by a feasibility demonstration phase andevaluation of models on respective tactical vehicles.

FACTS: The state-of-the-art in conformal antenna technologycan be pushed to assess the feasibility of replacing existingtactical vehicular antennas (HF and VHF) with a conformalantenna without a major reduction in communication range. Thebenefit realized from this is a lower profile antennapresenting less of a uisible signature for identification ofcommand post vehicles, as well as a safety margin from highvoltage power lines. Reduction in thermal, optical, andvisible profile, as well as radar cross section is a goal.

MILESTONES: FY92 Begin technical assessment.FY93 Complete technical assessment/initiate

feasibility contract.FY94 Complete feasibility models and conduct

evaluation tests on candidate vehicles.

POINT PAPER

OBJECTIVE: Development of ECCM enhancements for UHF LOS TransmissionSystems operating in Corps and Division areas.

FACTS:

1. The deficiency which the UHF ECCM Techniques WETS) Programaddresses is that there are no active electroniccounter-countermeasures (ECCM) incorporated into present UHF LOSTransmission Systems operating in Army Corps and Division areas to

allow reliable operation in an electronic jamming environment.

2. The [ey operational capability which is to be provided by theUETS development is to allow survivable communications when operating

during jamming. An added benefit of this development is that it will

also provide enhanced system operation in a bLnign nv.r.onment by

increasing link: margin and alleviating co-site interference.

Possible enhancements are an improved antenna system (i.e.,adaptive antennas, larger passive arrays), error correctioncoding/decoding, and increased transmit power for the AN/GRC-226.The AN/GRC-226 is the UHF multichannel radio used in the Mobile

Subscriber Equipment (MSE) system and operates in the -225400 MHz

(Band 1) and 1350-1850 MHz (Band 7) frequency bands; since the error

correction coding will be accomplished at baseband one design willsuffice for both frequency bands. A more complete description ofthese techniques follow:

(a) Error rur(-ction Coding with Interleaving - Coding withinterleavink wil1 provide burst and random error correctioncapabilities to the MSE UHF LOS system and will be provided for twoapplications:

(1) Full Channel Coder (FCC): The FCC will be applied tothe complete 16 channel digital transmission group used in theNCS-SEN and NCS-RAU links.

(2) Selected Channel Coding (SCC): The SCC will be appliedto the routing (RSS) channel and common channel signalling (CCS)channels of the 32 and 64 DTGs used in the NCS-LEN and NCS-NCS(backbone) links, respectively. It is presumed that this coding will

be provided as a software enhancement to the TTC-46 and 47 switches.

19

(b) Improved Antenna System (IAS): The Improved Antenna System(IAS) will provide performance enhancement either throughreplacement or modification of the present antenna systems being used

in Band 1 and Band 3. The two IAS approaches follow:

(1) Active IAS. Tie aztive IAS will provide automaticnulling (cancellation) of unwanted signals whiie raaeiving thedesired signal.

(2) Passive IAS. The passive IAS will provide a reduction

in the reception of unwanted signals through the use of a new antenna

design with improved pattern characteristics.

(c) Power Amplifier (PA). The PA will provide an increase in

transmit power. It will require a duplexer to allow full duplex

operation.

4. Presently, the Army is formulating requirements for the ECCM

enhancements. Once they have been determined, a market Survey will

be performed to determine what is available to meet theserequirements. After this is determined, this information will be

given to the GTE Government Systems Corp. (MSE Prime contractor) to

determine the feasibility of integrating these enhancements into the

MSE system with minimum impact. Finally, once this determination is

made, CECOM will initiate an R&D program accordingly to build

prototypes for test and demonstration.

The UETS Program may consist of 2 phases. Phase I is for the

design, development, test, and demo of 3 prototypes of each

enhancement to insure feasibility of fit, form, and functionz Phase 2

will be a follow-on option to develop, build, and test 10 each

engineering development models to military specifications forproduction proveout. The initiation of Phase 2 will depend on the

successful demonstration of the protoypes developed in Phase 1 andavailability of PM MSE funds. The briefing presentation relative to

cost and schedule pertains to Phase 1 only.

POINT PAPER

SUBJECT: Adaptive Net Planner and Management (ANPM)

OBJECTIVE: The goal of the Adaptive Net Planner and Managementprogram is to develop the protocols and algorithms to provide a near realtime planner for localized network voice, data, and video subscribers. Alsoto develop the protocols and algorithms to provide OSI-based networkmanagement for localized networks. The near term focus for thisdevelopment is the SASTD 95 DEMO and the far term focus is the BIS 2015architecture.

FACTS: The ANPM protocols and algorithms would provide an automatedplanner capability for the localized network subscribers. The automatedplanner must operate in near real time to support frequent userrequirement changes as a result of battlefield dynamics and/or missionchanges. The ANPM design for the localized network will be based on thecurrent DOD protocols and algorithms. They will be enhanced to perform inthe tactical environment and support evolution to OSI compatibilty.

The near term planner will focus on the data subscribers in the localizednetwork environment consisting of FOTLAN, Wireless Lan, and ethernets.The results of the near term effort will be demonstrated in laboratorydemonstrations with transitions to the SASTD DEMO. The far term effortwill focus on voice/data/video subscribers in the localized network and OSIbased network management for broadband ISDN and metropolitan areanetworks.

POINT PAPER

SUBJECT: User Interface Technology

OBJECTIVE: User Interface Technology (HJIT) provides for the deve'opment,integration, demonstration and transition of next-generation soldier-machineinterface (SMI) technologies to standardize user-transparent/user-friendlyinterfaces to the Army Tactical Command, Control and Communications System(ATCCS) at all echelons and improve users interaction with ATCCS, enablinguser input, access, processing, and assimilation of battlefield informationefficiently in real time with little training.

FACTS: User requirements include the need for tactical user interfaces thatare natural, easy to learn and use, consistent across various systems andmachines, highly mobile and appropriate for geographically distributed C2systems to enable unsophisticated users to easily and quickly access tacticalinformation. These interfaces are critical to support the ever-increasingamount of voice, intelligence, logistics, imagery, and other C2 informationcollected from a wide variety of multipiatform/multispectral sensors andmultiple data inputs such as mouse, voice, joystick, etc. to insure that astandardized approach will result in handling input and output in the samemanner in different systems.

In satisfying these requirements, prioritization and human engineering arealso needed to determine the precedence of the manner in which informationthat must be input, processed, and ultimately displayed to military decisionmakers is handled for different systems. Significant improvements in theease of interface along with the reduction in the time needed to interactwith a C2 system will increase the efficiency of personnel, enablingplanning to be performed more easily and reactions to take place automaticallywithout specific directed effort. These attributes may lead to a reductionin the number of operational personnel needed by reducing the degree ofdedicated effort for machine interaction.

The availability of a consistent, simple, easy-to-use interface to allsystems is needed that will allow the soldier to improve effectivenessby performing necessary input/output functions more rapidly andefficiently, thereby freeing him to concentrate on survivability andother aspects of mission performance rather than on the mechanics ofhow to interact with computer systems. Through the application ofadvanced UIT, the capability to reliably access vast quantities ofdata and information to interrogate, display, and manipulate easilyand efficiently is expected to be possible without the need forextensive computer experience.

Whereas current ATCCS systems require standard keyboard or pointingdevice to interact with the system, require trained users, is prone toerrors, and is time consuming, UIT will demonstrate that userinterface to a C2 system can be humanly natural and machineindependent so that with ve-y little training, an unsophisticated usercan easily and effectively use a sophisticated and powerful C2 systemwith capabilities for user-friendly voice input/output; naturallanguage interface that will allow direct interaction with thedatabase frame structure in systems such as the the Maneuver ControlSystem (MCS) using voice as well as typed commands; advanced displaytechniques that use voice, data, video, imagery, maps, three-dimensionalcolor, and terrain information for vital C2; touch screens; flexibleself-defined menus; multimedia (voice, data, text, spreadsheets,images, maps, etc.) information systems, presentation synchronizationand real-time message exchanqe capability; advanced terrain reasoningand visualization; and video compression; all of which will serve todemonstrate enhanced transitional soldier-machine interfaces and enableflexible integration ot s()Idier proces.ses in an interactive environment.

HS8

Key operational capabilities to be achieved through improved UITinclude more thorough understanding of the battlefield situation,greater ability to visualize and evaluate the various optionsavailable, reliable user identification and voice authentication,fewer misunderstandings or mistakes due to confusion caused byinconsistent data presentations, reduced user workload and fatigue,and improved efficiency in stressful, time-critical situations.

UIT will be hardware independent through use of an open architecture,provide a standardized windowing environment for keyboard, display,and graphics pointing devices that will support future multimedia C2application programs, and perform the following subfunctions: SMIinitialization, SMI termination, display management, forms processing,overlay graphics processing electronic map background processing menuprocessing alert processing primitive object support printing.

UIT will provide hardware and software elements operating on ArmyCommon Hardware and Software (CHS) system the capability to: acceptmultimedia data input from the user or from sensors, manipulate andprocess the data into information that can be efficiently transported,and display or output the information in a multimedia format.

POINT PAPER

SUBJECT: Development of Automated Command and Control Battlefield Operations SystemsConcepts

PURPOSE: Using low cost, rapid prototyping capabilities, and existing and new automationsoftware applications or processes, develop, evaluate and refine automation applications.appropriate and applicable, to the execution of command and control processes for US Army unitsof brigade and below sizes regardless of mission dependence. Extend, integrate and enhance theATCCS concepts such that life cycle costs are reduced, or at a minimum, not increased-

FACTS:

" Present command and control for all units is not automated

" Present practices, procedures ani processes are not standardized relative to automation

" Both automation and its application to C2, and the practices, procedures, processes anddoctrine are evolving

• An interactive "developer" - "user" process based on rapid prototyping concepts canaccelerate and enhance fielding of automation aids for C2

• ACCS/ATCCS common hardware/softw,ire xtensions can minimize and/or reduceassociated life cycle and development costs.

OPPORTUNITIES FOR CONTRACTORS:

* Selection of low cost, graphical interface capable, government owned-supported RapidPrototyping software maximizes multiple contractor participation in modular applicationsdevelopment

• Although an integrated, seamless, command and control battlefield operating systemdevelopment is targeted, subsystem development, existing software insertion, and prototyping ofspecialized (unique) C2 needs. suggests a requirement for system software integration will exist.

• Rapid Prototyping, demonstration, evaluation and refinement require establishment.maintenance and support of B2C2 Functionality test Bed capability, possibly in several locations.Test support and test documentation is involved.

* Transitional documentaton preparation and software configuration management supportwill be required.

POINT PAPER

SUBJECT: Tactical Multinet Gateway (TMG)

OBJECTIVE: The goal of the Tactical Multinet Gateway (TMG) program is to

develop the protocols and algorithms necessary to evolve from themanual gateway capabilities of the current localized network environmentof the ATCCS to the automatic gateway capabilities needed for the near

term SASTD 95 demo and the far term BIS 2015 architecture.

FACTS: The TMG protocols and algorithms would provide automaticalternate routing and support gateway network management. They willsupport network dynamics such as topology changes due to node losses,connectivity changes. The design will be based on the current DOD MILNETalgorithms and protocols. The protocols and algorithms will be enhanced to

function in the tactical military environment. The protocol/algorithmdesign will support the evolution to OSI based gateways for the localizednetwork environment.

The near term effort will concentrate on a packet data gateway to

connect localized network data subscribers such as FOTLAN, Wireless LAN,and ethernets to the MSE wide area net. The results of the near term effort

will be demonstrated in periodic laboratory demonstrations and concluding

in the SASTD 95 DEMO. The far term effort will concentrate on a tacticalmultinet gateway to connect the localized network voice/data/videosubscribers with broadband ISDN, metropolitan area networks, MSE wide

area networks.

- Capacity requ ts for interocamuication between tactical andstrategic information processing facilities is rapidly expanding.Envisioned requiraents include transmissions links which supportultitudes of voice, video and data channels. Optimizing capacity

requires maximizing physical link bandwidth.

- Future transmission systs are now envisioned which exceed10Ops Optical transmission systens are the only alternative atthis bit rate.

- Tomorrows transmitters will be required to operate at loopsInternal Laser diode modulation is inherently limited toapproximately I8 s. Internal modulation is also inefficient interm of power oos.

KEY OPERATIONAL CAPABILITIES:

- GmAs modulators allow for the possibility of monolithicintegration with other existing GaAs architectures.

- Eternal modulation could theoretically far exceed the currentstate of the art.

- Multiple Quantum Well devices have dmonstrated pronoucedmodulation depths and improved efficiency over existing high speedoptical modulators.

- Phase modulation device development provides for a more generictechnology in that it allows for the anticipated low Operating budgetwithin coherent (heterodyne detection) commication systms whilestill providing for todays direct detection sches.

PROGRAM STRATEGY:

- The device wafer and Mamh-Zhender mask are curentlybeing fabricated at Photronics Inc. and Bllcor.respectively.

- Within the near future device processing will take placeit Princeton university, and device testing will take placeat both Princeton University and CECM Laboratorys.

- The future strategy is to transition the program to 6.2developaent of Fiber Optic wideband RF Links in FY-94.

FY 92 OBJE.tIVES:

- Qumplete fabrication of the Mach Zhender architecture forthe modulator, with subsequent testing and characterization.

- Simltaneous to device fabrication, work with Princetonin developing a proposal for the systems aWlicationdemonstration.

FtfnR PN:

- Work towards a high speed systems applicationdemonstration.

USER REQUIREMENTS/DEFICIENCIES:

Simulation of military communications systems can encompass 5000concurrent objects. Fitting simulations of this magnitude incurrent architectures forces modeling assumptions that compromisethe validity of the observed data. Partitioning a large model intoindependent" units run separately is justified only by computation

expediency - the real world system may not be separable in thecontext of the model's assumption. Aggregation of object clustersis another expedient that abridges analysis requirements as wellas obscuring comparison of simulation results with real worldmilitary exercise data.

KEY OPERATIONAL CAPABILITIES:

- Economically feasible combinations of computer hardware andsoftware that can accommodate large system simulations are needed.The desired ratio of simulation to real world time is less thanfive.

- Hardware candidates are restricted to what is currentgeneration machines. The goal is not speed up of hardware, butacceleration of simulation execution.

PROGRAM STRATEGY:

- Time event management of concurrent objects is a criticaldesign issue. What will work best 9

- Where is parallellism in discrete event simulation and to whatextent can distributed processors take advantage of it?

FY-93 OBJECTIVES:

- Answer the questions raised in program strategy.

FUTURE PLANS:

- Develop a candidate architecture based on design issuesidentified in FY-93.

Point Paper

SUBJECT: Modeling Methodology

OBJECTIVE: Develop a modeling methodology and environmentembedding support tools and databases for validation trails fromanalysis objectives to simulation code.

TYPE: Competitive

STATUS: 6.2 Development

SCHEDULE: Award Date 30 Oct 92Period of Performance 24 months

POC/PHONE: Robert Ros/(O8)544-2575

USER REQUIREMENTS/DEFICIENCIES:

- Modeling large systems such as tactical communications deployedon a battlefield is an ad hoc process at present. Althoughsimulation code is the end prodict, it does not clearly express themodel methods, concepts, and assumptions abstracted from analysisgoals and system referents.

- Structural validation of a system model is only feasible whendirect correspondences can be made from real system objects toabstracted models that are subsequently mapped to simulationimplementations

KEY OPERATIONAL CAPABILITIES:

- Future modeling requires a development environment thatintegrates and links explicit analysis requirements, modeldescriptions, and implementations. A real system object must belinked to referent material(specifications), its expression as anabstract description for a specified analysis goal, and itsimplementation in simulation code.

- The environment requires software tools to build, record, anddisplay the links and contents in the cumulative modeling andsimulation process that stems from analysis requirements.

- The environment will be implemented on the current generation ofworkstations. Potential hosts are restricted to those that arepresently available commercially.

177

PROGRAM STRATEGY:

- Define a model description basis that has a visiblecorrespondence to both referent and implementing software concepts.The description basis must serve as a bridge of mutualunderstanding between referent system experts and simulationsoftware engineers.

- Identify and specify the interfaces between analysis, modelin ,and implementation phases.

FY-93 OBJECTIVES:

- Complete specification of model description basis.

FUTURE PLANS:

- Complete interface specifications.

- Survey available tools. Adopt applicable candidates and developor modify new tools as needed.
