摘要
介绍了一种基于光纤光栅传感器的周界检测系统中的信号处理方法,即时频数据分析法。在时域信号分析的基础上,通过将时域信号进行频域转换来进行入侵信号的模式识别及分析,并利用MATLAB仿真计算结果加以验证。试验结果表明该方法可以提升系统识别不同的入侵行为的能力,解决了纯时域分析下难实现的模式识别问题。
This article introduces a digital signal processing method of Perimeter Intrusion Detection based on Fiber Bragg Grating （FBG）, which is the Time-Frequency analytical method. On the basis of the in-time signal analysis, It could finish the intrusion pattern recognition and analysis by transforming the in-time signal into the in-frequency signal and the results also are proved by using MATLAB simulation. This Time-Fre- quency analytical method resolves pattern recognition problem that exists in the pure time analysis.
