Here’s a review of the book Digital Processing of Synthetic Aperture Radar Data: Algorithms and Implementation by Ian G. Cumming and Frank H. Wong, assuming you’re referring to the PDF version commonly used in remote sensing and radar signal processing courses.

Once range compression is complete, the focus shifts to the more complex task of azimuth compression. This stage is complicated by "range cell migration," a phenomenon where a single target's signal drifts across multiple range bins as the sensor moves past it. Processing algorithms must correct for this curvature to ensure all energy from a single point is correctly integrated. The most common algorithm for this is the Range-Doppler Algorithm (RDA). RDA is favored for its computational efficiency, as it handles range and azimuth processing separately in the frequency domain. For high-resolution applications or wide-swath modes, more sophisticated methods like the Chirp Scaling Algorithm (CSA) or the Omega-K (Wavenumber) Algorithm are employed to handle the variations in signal characteristics more accurately. Often used for ScanSAR data, prioritizing speed and
