Abstract

In this paper a spotlight SAR raw signal simulator for extended scenes is presented. The proposed procedure has two main advantages: first of all, use is made of efficient FFT codes, thus reducing the computational load with respect to a time-domain simulation; in addition, the procedure is planned taking into account theoretical developments used in an existing stripmap simulator, so that most of the algorithms employed in that simulator can be reused after minor changes.
