Modified Range-Doppler algorithm using the exact range model

WU Zhao-xian,HAN Song(Institute of Electronics,China Academy of Science,Beijing 100080,China)  
In this paper a modified Range-Doppler algorithm in squint mode SAR is presented using the most exact range model.Four range models are given.Three R-D algorithms already existed and the one presented in this paper are mapped one-to-one with the four models.Differences of four R-D algorithms are pointed out.The simulation of four R-D algorithms demonstrates that the modified algorithm meets the requirements most exactly in squint mode imaging.
