摘　　要：分析了中低轨卫星及星载红外传感器对导弹目标的可探测性因素,提出了几何可见、光学可见和设备可见的概念,建立了单星对导弹的可观测模型。对Walker-δ星座的3*7,7*3两种构型进行了仿真,讨论了传感器工作模式和作用距离的影响,以及可见率的数值特性,并演示了3个任务对单弹道接力跟踪的典型情形。The ballistic missile surveillance based on MEO and LEO constellation with infrared sensors was analyzed in this paper. The detectabilities of geometry, optics and equipment were put forward. The model of the single satellite for the missile was established. The ballistic missile surveillance with two structures 3＊7,7＊3 of Walker-δ constellation was simulated. The effectiveness of the sensor operation mode and operation distance and the numerical characteristics of the detectable ratio were discussed. The relay trackings of the single trajectory for three missions were displayed.
