A technique of speckle reduction in synthetic aperture radar(SAR) images was presented.
提出了一种新的SAR(Synthetic Aperture Radar)图像降噪方法,利用小波变换对空间位置信息保留的特性,依据小波变换后近似图像仍满足吉布斯分布,将模拟退火算法引入到小波域中,首先,根据SAR功率图像斑点的特性,对传统的同态变换方法做出了相应的修正,大大降低了处理结果的辐射偏差,提高了等效视数,然后在多分辨率理论和小波变换理论基础上,选用适合特定图像的最优小波基进行分解,最后对小波变换后的近似图像进行模拟退火处理,对各个细节图像有选择地进行软阈值处理。
