摘要：
As an effective measure for generating large-scale three-dimensional surface location information and accurate digital elevation modeling (DEM), InSAR is an important research direction in radar research fields nowadays[1]. However, there exists flat-earth-phase in InSAR, thus the step in the InSAR process that removing the flat earth effect is necessary. Though the back projection imaging method, the flat-earth-phase in InSAR system could be removed accurately in theory. Further, the flat-earth-removing of BP method for InSAR system has been proved in this paper based on the actual Ka-band InSAR data. To ensure the phase-preserving capacity, the IMU data must be used for accurate motion error compensation.
