SAR-Mosaic very different colors in RGB mode

Microwave Toolbox
#1

Hello,
I downloaded and preprocessed different Sentinel 1B IW GRD Scenes. Now I wanted to fuse them into one big mosaic. The Mosaicing worked but the colors in the image are very different, when I use “open rgb image window”. Also the db values differ. Is there anything I can do about it?

My preprocessing workflow looks like that:

this is my mosaic

The problem becomes particularly clear in the middle of the image, especially because “sharp edges” are created on places, which were taken on the same day, that’s what I don’t understand.

Best regards

as you have radiometrically calibrated all images, please disable the “normalize” option in the SAR Mosaic operator. Larger feathering is fine.

Thank you for the fast reply. I will try it right now. Processing will take about 8 hours, I will then report how it went!
Edit: It worked fine, perfect mosaic now! Thank you very much!
