摘要：In this paper, we proposed a new Distributed SAR Satellite(DSS) using one passive satellite with a dual receive antenna(DRA) flying in formation with an already existing conventional SAR satellite. Such system can provide either GMTI or INSAR functions or both. However, the complexities of DSS imaging increase due to the synchronization problems and Baseline estimation problem. Accuracy requirement for baseline estimation and synchronization are given. A method based on dual frequency GPS is introduced to solve the Baseline estimation and time & frequency synchronization problems of Distributed SAR Satellite
