摘要
Abstract
Based on the parameters of Germany's TanDEM-X format flying satellites Interferometric synthetic aperture radar(In-SAR)system,the method of phase synchronization of InSAR system by single frequency continuous wave duplex is addressed.The framework for the implementation of this synchronization method is given in the paper,the expressions of the theory on the phase synchronization method are deduced,and the factors of effects on the accuracy of the synchronization method are simply analyzed.This phase synchronization method can be used to space-borne bi-static and multi-static SAR synchronization link design.The syn-chronization method is validated by numerical simulations.Moreover,the engineering accuracy is tested and verified through an ex-perimental system.Results show that the accuracy of phase synchronization on carrier frequency is depend on the frequency accura-cy and consistence of frequency multiplier.The method of phase synchronization can be used to the design of systems similar to TanDEM-X or other similar systems.关键词
