摘　　要：天基雷达在广域目标监视方面具有独特优势,利用天基雷达实现广域海面目标跟踪具有重大现实意义和特殊难度。针对天基分布式雷达体制,在分析其用于海面多目标跟踪场景所存在的区域非均衡覆盖、低/超低回访周期、实时处理等特殊问题影响基础上,提出了星间接力跟踪处理方式和栅格化跟踪处理框架,并给出了相应的多目标跟踪性能评估指标体系。仿真评估结果表明了所提栅格化跟踪处理框架相对常规全域处理框架的优越性以及评估指标的合理性。Space-based radar(SBR)has unique advantages in wide-area target surveillance,and it is of great practical significance and special difficulty to realize wide-area sea surface target tracking using SBR.Based on analyzing the effects of special problems such as regional unbalanced coverage,low/ultra-low return visit period and real-time processing in application to sea surface multi-target tracking scene for space-based distributed radar system,the tracking processing mode of inter-satellite relay and the tracking processing framework of rasterization pertinently are put forward,and the corresponding multi-target tracking performance evaluation indicator system is presented.The simulation evaluation results show the superiority of the proposed tracking processing framework of rasterization relative to conventional global processing framework and the rationality of the evaluation index.
