Abstract :
A complete interferometric synthetic aperture radar (SAR) simulator has been developed. It achieves precise results by using geodetic models to represent the Earth´s shape, and considering SAR effects such as range migration, Doppler shifts, or perturbations of movement in the airborne case, which are included via the inverse Extended Chirp Scaling Algorithm (ECSA)
