Abstract
A monostatic microwave sensor has been developed which can compliment or provide dual technology with microwave bistatic sensors used in many nuclear facilities. The monostatic sensor provides target signatures and detection patterns uniquely different from bistatic sensors. Although the microwave transceiver has been used for indoor applications for over 20 years, outdoor use has been limited because of inability to discriminate against small targets close to the antenna such as rain on the radome and large targets beyond the range of the protected area. A monostatic sensor recently developed has a modulation technique along with appropriate signal processing in the receiver that rejects targets beyond a predetermined range and also attenuates the reflections of small close in targets.
