Keywords: airborne, SAR, IMU/DGPS, attitude compensation, motivation compensation, DEM generation Abstract. The DGPS/IMU can measure position and velocity extremely high, and it is widely used in air-borne InSAR system. The passage based on the DGPS/IMU's action in the airborne InSAR system, makes sure the interference phase accuracy, from the analysis of the interference phase accuracy influence by InSAR imaging motivation compensation makes sure the interference phase accuracy, and analyzes the system's request of DGPS/IMU from the DEM accuracy's influence by DGPS/IMU's surveying error. At last the paper advances the accuracy request of the DGPS/IMU system, and provides basis for the InSAR system's selection of DGPS/IMU system.
