The In-orbit Test Method for Distributed InSAR Satellite Azimuth Space Synchronization

The distributed satellite InSAR (interferometric synthetic aperture radar) system is currently an important and excellent remote sensing method for obtaining high-precision Digital Surface Model (DSM). In order to achieve InSAR interferometry, it is necessary to ensure the space synchronization of the binary satellite SAR beams, so as to provide the auxiliary satellite to receive enough echo energ...
