| 摘 要： | 探讨了抑制合成孔径雷达 (SAR)图像相干斑噪声的方法。传统噪声抑制和近年来小波变换去噪方法都有其不足之处。将小波变换和维纳滤波结合用于抑制SAR图像相干斑噪声 ,能够获得良好效果。通过比较观察在多个小波基情况下的噪声抑制结果 ,可以选择较好小波基 ,从而有较好的相干斑噪声抑制和保留图像边缘与点目标的滤波效果。

| Abstract: | Methods of reducing speckle noise in SAR image are discussed in this paper.Traditional methods and recently wavelet transform for reducing speckle noise have some shortcoming,this study has satisfied result for reducing speckle noise by combining wavelet transform and Wiener filter.The better result of reducing speckle noise in case of preserving image edge and point target is presented by selecting the better wavelet basis after these effects are compared and observed. |
