摘要 对分布式小卫星SAR系统地面动目标检测GMTI模式的研究目前正处于广泛探索阶段。如何评价一个分布式卫星系统的GMTI能力,编队构形对GMTI到底有怎样的影响,怎样设计编队使系统GMTI能力最强等问题是文章讨论的内容。从盲速比例的角度出发,提出对系统的GMTI功能进行衡量的定量指标,分析编队构形方式对该指标的具体影响,寻找GMTI模式下可能的编队优化方法。 Distributed Spacebased SAR (DSS) system Ground Moving Target Indication (GMTI) mode is now explored widely. Three questions, how to evaluate the system GMTI function ability, what's the formation effect on the signal processing, and how to design a formation to maximum the GMTI performance, were discussed in this paper. Improvement factor and blind velocity percent were used as the formation optimization metrics. Simulation compared the optimal result and the Minimum Redundancy Arrays.
