| Abstract: | A real-time SAR simulator for natural scene's echo is designed and implemented based on TS201 processor.Firstly,the simulation model of echo simulation is presented.Secondly,the three key techniques are analyzed.Finally,the experiment results about point and natural scene are shown to the accuracy and real time of the simulator.The simulator generates SAR echo signal according to the updated radar flight trace in real time,and it can supply simulated raw data for real-time imaging processor and algorithm. |
