Abstract
ABSTRACTWe propose a chaotic guided radar for perimeter intrusion detection and experimentally demonstrate the corresponding radar prototype which includes a transmitter, a receiver and two leaky coaxial cables (LCXs). A wideband Boolean-chaos signal is generated in the transmitter and served as the probe signal. An electromagnetic surveillance area is formed between two LCXs which act as transmitting and receiving antennas. The receiver can accurately locate an intruder crossing the LCXs by measuring a variation of correlation traces before and after intrusion. Experimental results demonstrate the proposed radar can realize the simultaneous detection of multiple intruders with 50-cm range resolution and 35-dB dynamic range. Furthermore, the anti-jamming property of the proposed guided radar for radio frequency interferences and noise are also demonstrated experimentally, which makes it perform superbly in the detection environment with multiradar cooperative work and noise.
