The relative motion between the sensor and target induces a Doppler frequency shift in the azimuth (flight) direction, which is essential for focusing the image. Data Types:

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. The relative motion between the sensor and target
