Hello everyone, I am working on SAR imagery and have encountered an issue with SAR-simulation terrain correction. Although I am using the same data and following the exact same workflow each time, the correction results are different. I was wondering if anyone else has experienced a similar problem. The terrain correction uses an external DEM with the “externalDEMApplyEGM” option unchecked. The processing steps are: radiometric calibration, generation of the coherence matrix, filtering, and terrain correction.
