Simulation Study on Multi-Frequency Signal Detection in Perimeter Intrusion Detection System by Matlab

Abstract:

Multi-domain perimeter intrusion detection system by one machine is based on leaky cable. To solving the problem that the multi-frequency electromagnetic disturbance signal detection circuit is complex and repeated, a method is raised, which is without processing by different frequency, sending the intrusion disturbance signal from multisport to processing circuit to perform FFT, contrasting it with signal spectra without disturbance by frequency analysis, and determining if intrusion happened, the number of intrusion case, detailed place and domain. Simulation study is performing by Matlab, which demonstrated the feasibility and advantage in the project.
