| Abstract: | This paper covers a correlative method of suppressing speckle in high resolution airborne SAR(images.) Firstly,the advantage of the wavelet transform is pointed out.Secondly,we studied the characteristic of the high resolution airborne SAR images and presented a method based on wavelet transform.We use the complex wavelet transform in this method.Finally,the experiment results show that this technique presents(superior) results than those obtained from other methods. |
