Digital processing of SAR data is a computationally rigorous task requiring precise signal processing techniques. The transition from raw echo signals to geocoded imagery involves critical steps of range compression, migration correction, and azimuth focusing. While the Range-Doppler Algorithm remains the industry standard for moderate squint processing, modern implementations increasingly utilize Chirp Scaling and Omega-K algorithms for higher precision requirements. Transforming raw "echo" data into a viewable image

In raw format, a single point target (like a corner reflector) appears as a defocused hyperbola across several hundred range and azimuth lines. This spread is due to two factors: In the Range-Doppler Algorithm (RDA), this is performed

RCMC is the process of shifting the signal energy so that the trajectory becomes a straight line parallel to the azimuth axis. In the Range-Doppler Algorithm (RDA), this is performed in the Range-Doppler domain (range frequency, azimuth time) using interpolation kernels.

) Algorithm: Also known as the Wavefront Reconstruction Algorithm, it is used for high-precision imaging and wide-angle cases.

The book is designed for both algorithm developers and system engineers. It is structured into five logical parts:
