SLC to GRD graph problem


when using the SLC to GRD graph on S1A_IW_SLC data I receive surprising outputs (looking similar to the attached file). When I manually reconstruct the steps, I find that the problem first occurs after Thermal Noise Removal (before, with either Sigma0 or Gamma0 the image looks as expected). Accordingly, the attached screenshot shows an S1A_IW_SLC image which was radiometrically corrected (gamma0), and noise was removed, yet it has not been debursted.

Yes, this is a problem with the noise removal if it is after calibration. We’ll fix this soon. If you do thermal noise removal and then calibration you should have this problem.
