Unlocking the Earth from Above: A Guide to Digital SAR Data Processing
Step 4: Azimuth Processing Generate the azimuth matched filter based on the Doppler rate. Apply azimuth FFT, multiply by the filter, then inverse FFT. digital processing of synthetic aperture radar data pdf
Range resolution is achieved by transmitting frequency-modulated (FM) pulses, or "chirps". Phase History: Unlocking the Earth from Above: A Guide to
Chirp Scaling Algorithm (CSA): Avoids interpolation by using phase multiplies in the frequency domain, ideal for high-precision processing. Omega-K Algorithm ( Pros: More accurate than RDA for high-squint modes;
