Paper Abstract

A prototype through-the-wall surveillance system is being developed for use by law enforcement personnel that utilizes high power ultrasonic transducers to detect and locate stationary or moving people inside either metallic or non-metallic walled enclosures. Details of the prototype design will be presented together with recent data and analyses. The sensor is being designed as a field-portable unit with a real-time display of the location, in range and azimuth, of each detected individual. Applications of this technology include detecting and locating unconscious, sleeping, hiding, tightly bound or otherwise stationary people, as well as moving people, inside an enclosed area. The sensor should also prove useful in border patrol applications for inspecting vehicles and shipping containers at points of entry.
