Recently i’m doing my thesis,I want to add noise to sentinel-1 SLC product to get noise disturbed SAR bmp file,I download slc product,then I use python code and rasterio to read tiff files in measurement folder, add noise in it and save them.Then I use SNAP 9.0 to apply obrit file,calibrate and deburst to get .dim file that are noise disturbed.Then export it as bmp file.I’ve just konw a little about the theory so I wonder if the above process is right or not. I would be grateful if someone could telll me.
