摘要：

Along-Track Interferometric (ATI) SAR can be used to measure the radial velocity of ground moving targets. By using distributed satellites system the metrical accuracy will be improved and the measurable radial range will be increased. The key point of guaranteeing the distributed satellites system performance is to design the formation of the satellites appropriately. A velocity metrical accuracy model is developed to estimate distributed satellites SAR system performance. This model can be used to optimize the satellite formation of distributed satellites system which moves on flying around orbit. Finally, it is validated by simulation using randomized search algorithm, and the simulation results demonstrate the efficiency of the method.
