Abstract

Under the precision constraint of interferometric SAR simulation applications, a range frequency fast algorithm is proposed to increase the InSAR raw signal simulation efficiency and the GPGPU technique is used to implement the raw signal simulation of large 10km×10km nature scene. The experiment results validate the proposed fast algorithm and the GPGPU technique. The total speedup of GPU over CPU is 4, and some local grogram speedup is over 14, which makes the InSAR raw signal simulation more practical in the InSAR system simulation.
