COTS Technology The DS3 resides on commercial off-the-shelf computer workstations and its graphical user interface implements commercial Windows conventions, all of which result in several advantages:

• MicrosoftWindowsbasedsystems arefamiliarandeasytooperate,reducing training time

• PCbasedplatformsresultinlowerhardwarecostsandusemany existing drivers, utilities and analysisapplications

• Sparesandtechnologyupgradesarereadilyavailablefrom numerous vendors

• Manufacturerwarrantiesconveytothesystemowners

NorthropGrumman’sDistribu-ted Simulation and Stimula-tionSystem,alsoknownas

DS3,provideshighfidelitysensorsimulation for a multitude of sensors, including rotating radars; phased arrayradars;andidentification, friend or foe transponders.

DS3’s tactical environment simulator stimulatescombatsystemswithsensor, navigation and weapon systeminputs.Anadaptable,modu-larandscalableDS3architectureaccommodates emerging require-mentsbroughtaboutbytheneedtotest,trainandcertifycombatsystemevolutionsinresponsetorapidly-changingthreats.

How It WorksDS3shareshigh-fidelitysimulationsofair,surface,andballisticmissiletracksoveraDistributedInteractiveSimulation(DIS)-compliantnetworkandcommunicateswithtacticalsys-tems in real time. The DIS interface enablesadditionalDS3stoaccom-modate other interfaces or multiple platforms under test with the same simulated environment, and inter-connects with other DIS-compliant simulations.

The DS3 simulates motion and activi- ties of thousands of air and surface trackssimultaneouslyandmodels sensors and the environmental ef-fects on them. These effects include terraintrackmasking;displayand sensor effects such as track suppres- sion, multipath, ducting, and radar accuracy;cluttersuchasstormcloud, surface clutter and specular clutter(short-durationtracks).
