Abstract
Digital Elevation Model(DEM) can be obtained by using distributed satellites Interferometric Synthetic Aperture Radar(InSAR) system to obtain high-precision DEM of the parameters of the InSAR system need to be optimized.After a research on the correlation among interferential signals of the distributed satellites InSAR system
the author has presented a criteria for optimizing distributed satellites InSAR system parameters
and optimized visual angle
signal bandwidth and baseline.The author has also proved that the optimization under single-view processing is consistent with that under multi-view processing.
