Abstract

In order to obtain high-precision DEM in the worldwide, the InSAR system of two satellite formation working in the mode of one transmitter and two receivers must maintain the interferometric phase accuracy between two satellites. The internal calibration technology is used to extract and compensate the phase of InSAR system channel to ensure the phase accuracy. Based on the composition and principle of the formation satellite InSAR system, considering the composition of the system phase error, and according to the phase synchronization design method of the phase synchronization transmission and reception links, this paper designs the internal calibration link, carries out the test, and finally gives the implementation suggestions for the internal calibration project.
