Assuming you have your copy of the Cumming & Wong PDF open, here is the step-by-step digital processing chain you will code:
It performs a change of variables known as Stolt interpolation to perfectly handle range-azimuth coupling. digital processing of synthetic aperture radar data pdf
The processing system calculates an azimuth reference function based on the platform's velocity, wavelength, and target range. Assuming you have your copy of the Cumming

Raw SAR data, often distributed as Level-0 products, must first be decoded from the space packet protocol formats used by satellites such as Sentinel-1, ERS-1, and RADARSAT. This involves unpacking the telemetry data, performing range deskew (if using dechirp-on-receive), and converting to a format suitable for processing.
Digital Processing of Synthetic Aperture Radar (SAR) Data: Algorithms and Implementation
However, the raw data acquired by a SAR system is not an image. It is a complex, defocused, and range-compressed signal that requires extensive to form a coherent image. The primary reference for this field is the foundational text: Digital Processing of Synthetic Aperture Radar Data: Algorithms and Implementation . 1. Fundamentals of SAR Data Processing
