Melpar Division Physical Security Laboratory of E-Systems, Inc. has developed a monostatic quadrature range-gated pulse doppler radar sensor that uses digital signal processing techniques to detect intruders at outdoor locations or noisy interior spaces.
The company developed the system under contract to Sandia National Laboratories, which is under contract to the United States Air Force Electronic Systems Division. The sensor can be carried by a person and can be used to protect parked aircraft, mobile vehicles, stored weapons, or other strategic assets. The sensor resulted from 4 years of research that focused on clutter sources and the radar signature of humans in both upright and prone positions. The system was modified following the construction and field testing of an advanced development model. The system is highly accurate in distinguishing between intruders and clutter signals. It also detects tampering and tests itself to verify that it is operating properly. Figures and table. (Author abstract modified)
