摘要
本文分析了小波变化检测突变信号的原理,利用小波变换模的极大值和信号突变点的关系,结合Haar函数和dbN函数,在MATLAB平台上进行仿真测试,给出实例分析。结果表明,小波变换在信号突变性检测方面具有优越性,适合用1于测物雷达的信号处理中去,具有广泛的应用前景。
This paper discuss the principle and method based on the singular signal detection using wavelet transform.With the relationship between wavelet transform modulus maxima and singular point,the signal singular point location can be analyzed.Use Haar and dbN wavelet to simulation in MATLAB and the example is taken, the conclusion that wavelet transform have specific property for singular signal detection and location analysis. Can be well used in signal processing of Radar detection.
