| Abstract: | This paper discuss the principle and method based on the singular signal detection using wavelet transform.With the rela- tionship 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. |
