High-Power Stealthy Acoustic Through-the-Wall Sensor

"We have demonstrated a capability with ultrasound to detect and locate even stationary persons through certain interior walls at ranges up to about 8'. The Phase I program objective is to develop and demonstrate a proprietary high-power upgrade to thiscapability. Starmark's novel system concept should increase the power of the recently developed through-the-wall sensor by up to a factor of 100,000 in the Phase I breadboard and 900,000 in the Phase II prototype. The upgrade will make possiblesurveillance of persons through many more types of exterior building walls, including metallic walls, and over much greater ranges.In Phase I, we will design, build, test, and demonstrate a high-power, high-frequency monotone transmitter optimized for a through-the-wall sensor. In the Phase I Option, we will test and demonstrate the transmitter operating through a variety ofrealistic external walls, and we will produce a conceptual design of a Phase II system. In Phase II, we will integrate an array of the new high-power transmitters with the by-then completed acoustic through-the-wall sensor from the ongoing Air Force/NIJprogram, and demonstrate the performance of prototypes in stealthily detecting multiple persons through exterior walls and displaying their locations. This proprietary development will extend by orders of magnitude in power the capabilities of the recently developed acoustic sensor to locate stationary and moving persons thr
