  • In the application of distributed-satellite INSAR system for velocity-measurement of ground moving targets, due to the satellite clusters flying around, the flying tracks of all satellites are not parallel and their velocity vectors are different. This may cause the along-track baselines time-variety, affect the interferometric phase map and result in velocity and position measurement errors. This paper analyzes the clusters actual flying tracks and the influence of non-parallel flying to the ATI-SAR velocity-measurements precision, establishes the velocity-error model caused by non-parallel flying, proposes two novel methods to improve the measurement accuracy and obtain precise measurement. Finally, the simulation experimental results prove the conclusion proposed.
