SAR Image Quality Enhancement Algorithm

After the radiometric calibration of SAR images, the brightness of the pixel units reflects the size of the microwave scattering capacity of the features. However, there are still some inherent defects in SAR images that need to be remedied, otherwise it will cause difficulties in the subsequent image interpretation. In this paper, we will analyse the mechanism of coherent spot suppression, its impact on millimetre band, and applicable suppression algorithms from the perspective of coherent spot suppression.
