Through-Wall Sensing (TWS) Technologies for Dismounted Infantry

Time Domain Coporation (TDC) will develop a man-portable device that detects nearly motionless persons through walls. The resulting Sense Through The Wall (STTW) device will operate without external stabilization. With this device, soldiers in urban environments can quickly and safely assess building occupancy and maintain a tactical advantage. TDC's SoldierVision STTW device can operate in a non-stabilized standoff mode, and, when stabilized, can detect fine motions associated with breathing. TDC proposes to improve SoldierVision to achieve both functions simultaneously. After evaluating approaches for measuring platform motion, TDC will select the method that best meets the STTW application. TDC will implement algorithms to compensate radar data for platform motions and demonstrate the performance using a SoldierVision unit and Radar Testbed. TDC will assess the applicability of breathing detection algorithms and identify issues associated with implementing those algorithms in SoldierVision. The final solution will combine stabilization techniques and improved breathing detection algorithms. The Phase I effort will result in a system architecture for the stabilization solution. This architecture will facilitate the Phase II effort to produce an auto-stabilized SoldierVision prototype. During Phase I, TDC will identify integration issues in order to mitigate Phase II risks.
