双漏缆电磁耦合传感器设计
Design of the electromagnetic coupling sensor based on double leaky coaxial cables
摘要
Abstract
In order to solve the security issues of the important facilities,districts and national boundaries caused by a threat to terrorists and other insecurity factors,it is an urgent need that the intruder detection system is designed by new technologies and methods.Based on the double leaky coaxial cable,a novel electromagnetic coupling sensor is structured, its working principle is analyzed with the array antenna theory,the transmission characteristic of the port is simulated by the electromagnetic simulation software HFSS,and a new approach to designing the electromagnetic sensor is put forward. According to the national standard,the HLRHTCYZ-50-42L leaky coaxial cable with the operating frequency of 40 M Hz is selected as the simulation model,the electrical performance of the model is simulated and optimized,the changes of the transmission attenuation and coupling loss with the length and inclination of LCX's aperture are obtained.The electrical characteristics of the single LCX are measured,the coupling losses ( 95% ) of the horizontal and vertical orientations are 62.6 dB and 64.3 dB,respectively.The measured results are in agreement with the simulation results.关键词
