Biometrics-at-a-distance

The DOD has a need to leverage state of the art technologies remotely detect, collect, and evaluate physiological signals of interest. Applications and concepts-of-operations (CONOPs) that would benefit from this capability include, but are not limited to: building-clearing, warfighter health monitoring or battle damage assessment and triage, situational awareness and assessment. The main goal of the Biometrics at a Distance is to build a handheld device that detects multiple personnel in challenging environments. Omnevia proposes to build such a device based on our previous efforts, 1.) 300"Line of Sight (LOS) radar, 2.) 70"Rubble radar and 3.) MOPP4 (through clothing) radar. Challenges include penetration of clothing, walls/doors/windows and the fact that the cross-section of the target is so small. Omnevia proposes an array technique with (30 billion times) less stringent timing requirements called, cyclostationary. Essentially, data from the nodes is cross-correlated to search for matching repetitive patterns. As long as Heart Rate (HR) and Respiration Rate (RR) signals from two different nodes overlap in time, they will correlate as array gain. These devices set new standards for personnel detection in challenging environments. Omnevia personnel used the radar to search for victims at the World Trade Center in 2001. Heart Rate (HR) and Respiration Rate (RR) radar(s) developed by Omnevia engineers were utilized at the World Trade Center to search for victims after the 9/11 attack and were tested at Texas A & M"s"Disaster City,"so Omnevia"s advanced technology is well proven in an R & D sense. However, the technology was never carried-through to operational capability.
