Need help implementing an autofocus algorithm for the stripmap mode SAR image. I made the algorithm that receives an SAR image, but I can’t apply autofocus in any way. The type of algorithm does not really matter; I tried to apply the phase difference algorithm and the PGA algorithm. I will be glad of any help.

You will find some codes for PGA autofocus for spotlight SAR on github https://github.com/nnaka/sar. But you need to preprocess the stripmap SAR signal in order to apply PGA to it.
