The book is organized into three major parts:

Platform Flight Direction (Azimuth / Along-Track) =========================> | | | Look Angle (θ) | v +---------------+ / / / Swath Width / / / +---------------+ Slant Range (R) / \ / \ v v Near Range Far Range <-----------------------> Ground Range Coordinate Systems

varies variations along a hyperbolic curve. Because this range changes by an amount greater than the range resolution cell size, the target's echo energy drifts across multiple range bins during the aperture time. This effect is known as . digital processing of synthetic aperture radar data pdf

from a single point target can be mathematically modeled as a two-dimensional coupled equation:

RCMC must be executed prior to azimuth compression to realign the energy of a single target into a single range column. The correction is computed in the Range-Doppler domain (Range-Time, Azimuth-Frequency) where the hyperbolic migrations turn into linear or quadratic trajectories that are easily corrected using interpolation filters. Step 3: Azimuth Compression The book is organized into three major parts:

Synthetic Aperture Radar (SAR) is a sophisticated imaging technology that overcomes the physical limitations of antenna size by using the motion of a radar platform—such as a satellite or aircraft—to "synthesize" a much larger antenna. This allows for high-resolution ground imaging regardless of weather conditions or time of day.
