Chirp scaling algorithm
WebThe chirp scaling algorithm (CSA) was developed specifically to eliminate the interpolator used for RCMC [1]. It is based on a scaling principle described by Papoulis … WebThe Chirp-Scaling Algorithm (CSA) is one of the most widely used synthetic aperture radar (SAR) image reconstruction method. It has the bene t of eliminating the interpolation for the range cell migration correction. However, CSA s applicability is limited to straight ight trajectories and monostatic SAR.
