: High-resolution in the "range" (cross-track) direction is achieved using pulse compression techniques, often via fast convolution with a reference function.
This is not a beginner’s first radar book. The authors assume you know what range and azimuth mean, understand FFT properties, and have seen a matched filter before. Newcomers may find the first two chapters terse. Also, the PDF version lacks any interactive code (you’ll need to transcribe the pseudo-code manually), and some of the notation feels dated (e.g., using ( \tau ) and ( \eta ) for fast/slow time takes getting used to). digital processing of synthetic aperture radar data pdf
