Area Intruder Track Study.
Abstract
An investigation is made of a VHF bistatic doppler intrusion tracking system. A single CW transmitter illuminates an annular ring of 108 square meters, 8 km from its center. Multiple receiving sensors detect reflected signals from an intruder up to 1.5 km and compares its rotating phase with the direct signal. A data link connects all the sensors to a central computer which determines the track of the intruder. The track is visually displayed on a CRT and/or hard copy. Both theoretical and test measurements were made to verify the signal-to-noise ratios, probability of detection, and false alarm rates. Although the original system was to be used in a Hybrid Sensor System (HSS) as a tracking device, and the supporting sensors were to be used to make the initial detection, a scheme has been devised to provide both the detection and tracking functions.
