Synthetic Aperture Radar (SAR) speckle filtering techniques can be classified into three categories: multi-look processing, statistical filtering and filtering in transform domain.

The wavelet transform is of good localization property in the domain of time and frequency, which provides a comprehensive application in processing acoustic wave.

This process of image processing of some geometric transformation, filtering, time-domain transform both airspace source, is a very good program, in the hope that useful to everybody!
