ANALYSIS OF A 'SEISMIC FENCE' FOR INTRUSION DETECTION (EXPERIMENTAL AND THEORETICAL RESULTS).

Abstract

The report describes experiments with an active seismic system for detecting the approach of personnel and vehicles and presents in detail a mathematical model for the seismic phenomena involved. In the experiments, a 'seismic fence' was set up between a seismic transmitter and a seismic detector located about 100 feet apart. A person walking between the two units is detected as a disturbance in the delicately balanced seismic loop. Data from field tests verify the validity of the mathematical model described. (Author)
