摘要

Synthetic Aperture Rada is capable of all-weather, high-resolution and wide-ranging imaging , which is an important remote sensing observation technology. Unlike optical remote sensing images which have relatively uniform image characteristics, SAR images will be affected by speckles, resulting in large random fluctuations in the image, interfering with image interpretation and post-application, s...
