Abstract :
This paper presents a microwave sensing system for wide-area surveillance that comprises two leaky coaxial cables, one for transmitting and the other for receiving. The sensor detects an intrusion by measuring the electromagnetic field level, which fluctuates when an intruder approaches and passes through the surveillance area. In this research, we have succeeded in specifying an intrusion point by applying the spread-spectrum technique. Results from a field test prove that the detection algorithm could detect the motion of an intruder without experiencing interference from shaking trees or rainfall
