s:This paper discusses the wavelet frequency domain analysis conducted SAR speckle the characteristics and advantages of wavelet analysis and comparison speckle noise frequency domain filtering of certain kinds of methods,combining previous threshold optimization,the ideological edge detection and edge characteristics of the direction put forward a new speckle filtering methods.Experiments show that the noise filtering methods,and various spatial filtering methods and frequency domain has been the wavelet method,the noise filtering in both reservations and information combined effect has risen markedly,to a certain extent value.
