Digital Processing of Synthetic Aperture Radar Data: Algorithms and Implementation by Ian G. Cumming and Frank H. Wong. Core Processing Algorithms

Digital processing of Synthetic Aperture Radar (SAR) transforms raw radar returns into high-resolution images and geophysical products. Key goals are range and azimuth compression, motion compensation, geocoding, speckle mitigation, calibration, and higher-level analyses (classification, interferometry, change detection). Major algorithms include matched filtering (range compression), Range-Doppler, Chirp Scaling, Omega-K (frequency‑domain backprojection), and time-domain backprojection for arbitrary geometry and spotlight modes. Processing chains balance computational cost, geometric fidelity, and radiometric accuracy. digital processing of synthetic aperture radar data pdf
