...Range-Doppler (RD) algorithm, Chirp Scaling (CS) algorithm), synthetic scenes, InSAR (interferometric) simulation including multiple terrain types (flat, conical), and polarization calibration techniques (Whitt, PARC, Quegan, Ainsworth). The readme states that these were research/learning codes, with experiments and reports, and no further maintenance is expected. InSAR (interferometric SAR) simulation and processing. PolSAR (polarimetric SAR) calibration algorithms.
