摘要
本文给出了一种基于小波分析方法的噪声抑制技术，它具有运算简便和能在保持原图精度的同时有效地降低斑点噪声影响的优点。更重要的是，它将噪声抑制与数据压缩过程同时进行，对ＳＡＲ雷达图像的处理取得了良好的效果。
A wavelet based noise reduction technique is presented in this paper. The method can significantly reduce the speckle while preserving the resolution of the original image with easy computation. More importantly, it can integrate the noise reduction and data compressing process, and yield good results on processing the SAR images. [WT5”HZ〗
