An RF Intrusion Sensor for Isolated Resources.
Abstract
The application of VHF techniques to the problem of intruder detection around isolated resources was investigated. A number of possible configurations are discussed and the results of some preliminary measurements are presented. It was found that the shape of the protected zone could be made toroidal or hemispherical depending on the deployment of the sensor cables. Operation at 75 MHz demonstrated the high sensitivity of VHF signals to adult intruders and their insensitivity to changes in ambient environmental conditions. Specific system responses in intrusions by a human and by an animal are shown. Both the radial and the circumferential sensitivity of the system to various modes of human locomotion (walking, creeping, crawling, and rolling were investigated). Finally, areas that need additional investigation are identified and some specific recommendations made. (Author)
