It performs a change of variables known as Stolt interpolation to perfectly handle range-azimuth coupling.
The Range-Doppler Algorithm is one of the most widely used methods due to its efficiency. It processes the data in the range-frequency/azimuth-time domain, making it ideal for large-swath SAR data. It typically involves range compression, RCMC, and then azimuth compression. 2.2. Chirp Scaling Algorithm (CSA)
The interferometric processing chain includes:
The choice of algorithm ultimately depends on the specific SAR system, required image quality, and available computational resources. digital processing of synthetic aperture radar data pdf
), typically expressed in decibels (dB). This standardizes images taken at different times, angles, or by different sensors for comparative scientific analysis. Terrain Correction and Geocoding
Processing raw SAR data into a usable image typically involves two primary stages of pulse compression or "focusing":
