[Abstract]
The theoretical model of spotlight mode SAR is constructed firstly, and the principle of spotlight mode SAR imaging is analyzed. Then three spotlight mode SAR imaging algorithms are discussed and compared, including polar format (PF) algorithm, chirp scaling (CS) algorithm and range migration (RM) algorithm. Finally the results of simulation are given.
