Dear Rich-Hall. First of all, thank you for your source code. However, when I run your code with the Sentinel1A Level0 Folder https://drive.google.com/file/d/1DBijEmVCP3qK1yR44wnEMIZb21hgdR81/view?usp=sharing It cannot give me correct image as bellow. Can you help me check again. Thank you so much. Image

Could you share some details of the data you are using? The example I have used has the satellite in basic Stripmap mode. Gneerally, the satellite operates in TOPSAR mode. This electronically steers the beam backward to forward while cycling between different sub-swaths. A lot of additional processing is required to process images acquired in this mode, detailed in the algorithm definition. Unfortunately I have not attempted to process data from this mode, I have stuck to the more basic Stripmap mode (with the beam in a fixed position relative to the satellite) in order to keep the processing simple.
