1.打开.mainsafe文件
2.轨道校正:Radar—>Apply Orbit File,勾上Do not fail
3.热噪声去除:Radar—>Radiometric—>S-1 Thermal Noise
4.辐射定标:Radar—>Radiometric—>Calibrate
(只选output sigma0 band)
5.相干斑滤波:Radar—>Speckle Filtering—>Single Product Speckle Filter
(Refined Lee滤波器)
6.地形校正:Radar—>Geometric—>Terrain Correction—> Range-Doppler Terrain Correction
