摘要

利用乘性点估计器(一种局部自适应的同态滤波器)对合成孔径雷达(SAR)图像中的散斑噪声进行平滑处理。滤波器的自适应是基于对散斑噪声的假设概率模型。给出了混合地形机载SAR图像的散斑平滑结果。

Smoothing of SAR image speckle noise by multiplicative point estimation filters

This paper investigates the smoothing of speckle noise in synthetic aperture radar (SAR) images using the multiplicative point estimator, a locally adaptive form of the homomorphic filter. The filter adaptation is based on an assumed probability model for speckle noise. Speckle smoothing results for mixed terrain airborne SAR images are presented.
