Before discussing processing, one must understand the physical acquisition. A SAR system is mounted on a moving platform (satellite or aircraft). As it travels, it emits a series of chirp pulses (linear frequency modulated signals). The raw data matrix—often called the —records the amplitude and phase of the return echoes.
Estimates biomass, classifies crop types, and monitors deforestation.
The digital processing of synthetic aperture radar data transforms raw, unfocused echoes into high-resolution imagery that has revolutionized Earth observation from space. Ian G. Cumming and Frank H. Wong’s 2005 textbook, stands as the definitive reference in this field – a 625-page volume that combines rigorous mathematical foundations with practical, hands-on guidance.

Cumming and Wong describe multiple estimation methods in Chapter 12, including:

Focuses data along the flight path. It leverages the Doppler shift of targets as the sensor moves to "synthesize" a kilometer-long virtual antenna from a meter-sized physical one. 2. Primary Processing Algorithms Summary PDF Reference Guide
algorithm provides exact focusing by solving the acoustic wave equation in the frequency domain. It handles RCM perfectly across all ranges using a process called (interpolation in the 2D wavenumber domain). While computationally demanding, it is the premier choice for wide-aperture, high-squint, or low-frequency (UHF/VHF) SAR systems where approximations used in RDA and CSA break down. Back-Projection Algorithm (BPA)
: Analyzes how surfaces alter the polarization of transmitted waves (e.g., Horizontal to Vertical). Digital processing yields land-cover classifications that distinguish between urban areas, dense forests, water bodies, and agricultural fields. Summary PDF Reference Guide
