摘　　要：为提高天基预警系统对多目标的跟踪能力,提出扫描传感器纬度区间扫描模式和凝视传感器目标群跟踪模式,并基于此种模式设计基于聚类的扫描传感器纬度区间扫描调度方法和凝视相机目标群跟踪调度方法。由于诸多传感器的工作模式、探测频率、测量误差、视场模型均不相同,推导不同探测频率、视线误差的多传感器联合观测跟踪的克拉美-罗下界计算公式。综合运用以上方法,建立多体制传感器综合调度优化方法。仿真试验表明,该方法比传统工作模式下的系统对多目标具有更高的跟踪精度。In order to improve the performance of space-based missile warning system in tracking multi-target, the latitude-zone scan mode and target-group track mode were proposed for the scanner and tracker respectively. Based on these modes, the scan sensor and track sensor management algorithms were proposed. For the multi-model sensors, their working mode, the scanning frequency, the measurement error and the field-of-view differ from each other, an observation tracking Cramer-Rao formula was derived. Finally, a multi-model senor management algorithm based on the above methods was proposed. Results show that the proposed algorithm has a higher tracking accuracy for multi-target than the system in traditional working mode.
