Covert Through Wall Sensing with MEMS Radios

Intelligent Automation, Inc. (IAI), proposes through the wall sensing system consisting of a network of expendable local area MEMS sensors. The key innovation of our work is detection of persons moving behind walls or inside buildings using the RF communication link itself. IAI has effectively tested narrowband MEMS radios networks for intrusion detection nets that offers the following key innovation factors for a covert through-the wall-sensing-system: (1) sense through the wall, movements of human a intruder behind the wall (2) distinguish intruders movements from objects far away (2) distinguish fluctuations due to vehicular intruders, cell phones and other transmitters. (3) covertness and less sensitiveness to jamming (4) real time "distributed Intelligence" that distinguishes and reports position, velocity, direction of the moving object and resolve simultaneous detection of more than one moving intruder advancing in different directions and (5) dynamic Power management that reduces at least 50% memory usage.
