单机多域周界入侵探测系统中多频信号检测及仿真研究

Multi-frequency Signal Detection and Simulation in Single Machine Multi-domain Perimeter Intruder Detection System

针对基于泄漏电缆的单机多域周界入侵探测系统中FFT的应用问题,提出不仅可以改善该系统对单频电磁扰动信号的检测,而且可以实现对多频电磁扰动信号的检测,并应用Matlab对多点入侵扰动信号检测进行了仿真。

To the problem of using FFT in the single machine multi-domain perimeter intruder detection system which based on leaky cable,the using of FFT not only improve the detection of single frequency electromagnetic perturbation signal,but also realize the detection of multi-frequency electromagnetic perturbation signals is put forward,and used Matlab simulate the later part.
