Where we Started
Project Purpose and Objective
3
Purpose Develop a tool for first responders to locate live human victims in
disasters—such as earthquakes, structural collapses and floods— through the detection of beating hearts
• Using microwave radar, FINDER detects human heartbeats at standoff distances greater than 30 feet through walls, doors and rubble
• Allows effective allocation of search and rescue resources
• Helps first responders save lives through rapid victim detection and rescue
Objective Provide responders the ability to quickly determine if a live human is
trapped within a collapsed structure, allowing limited Urban Search and Rescue (US&R) resources to be sent to the location of a viable victim
Background
4
April 2012 – Initiated through a requirement from FEMA US&R Program Office
• Responders desired the ability to walk down a city street after an earthquake leveled buildings and quickly determine whether anyone was buried alive
• Same technology could vastly improve law enforcement officer and firefighter safety
• Project builds upon 4 years and more than $3 million of research conducted for the U.S. Army
Problem at Hand

Where do you start? Where do you end?
Looking for the Holy Grail of Search & Rescue (SAR)

“Walk down a street with collapsed buildings and readily determine which have live humans in them!”

FINDER Capabilities Detects Human Heartbeats and Respiration
• Search from 5-30 ft. away• Search results appear in less than 60 seconds• Detects multiple victims in the same location• Rejects non-human targets (distinguishes between a
human heartbeat and an animal heartbeat)• Radar RF output: 10 milliwatts at 3.1-3.2 GHz
Demonstrated Detection/Penetration Range• > 30 ft. of concrete, rebar, gravel and rubble• > 30 ft. of collapsed wood frame structure and appliances• > 15 ft. of stacked reinforced concrete slabs• > 100 ft. in open air or woodland• > 50 ft. through residential walls
Size, Weight and Power• 22 x 14 x 9 in (carry-on limitations)• Approximately 20 lbs• Waterproof (Ingress Testing IP67)• 14-hour rechargeable battery life
Used for Travel/Protection Sized to Fit in Airplane Overhead Compartmented
Search Strategy
10
FINDER covers an area twice as wide as far away (90 degrees) It’s not a hard cutoff, much more fuzzy Searches should be spaced about as far as the depth of search (30 feet)
to have overlap between search areas
How the Radar Works
11
Reflection off surface
Scattering from rubble, some goes towards target
Return from Target
Absorption in the soil
Radar illuminates the rubble pile (like a bright searchlight) and reflects everything, including the victim
But only if victim is moving (breathing and heartbeat)—look for tiny changes in reflection
Phase change is about 6º-7º due to small (1mm) motions of victim’s body due to heartbeat
Same for both continuous or pulsed radars; difference is in implementation
Multiple Antennas & Beams Allow Distinguishing Desired Targets from Others
12
Post-pilot, CPD will continue to integrate and test additional technologies through the duration of public safety broadband access.

Results
Reliability is combination of signal and “humanness”
Heart and Respiration rates are approximate; FINDER is not a medical instrument

Current Status
DHS/S&T work is competed
• Proof of Concept
• Field Trials: (OK-1, IN-1, VA-1, VA-2)
• Commercialization
Technology commercialized with two licensees
R4, Eatontown, New Jersey Spec Ops Group, Tampa, Florida
Develop other uses for the sensor
