摘　　要：针对星载雷达对弹道目标跟踪模式的选择问题,在建立星载雷达对空间轨道目标跟踪所需坐标系的基础上,给出了先转换后绝对运动状态跟踪和先相对运动状态跟踪后转换两种跟踪模式,分析了两种模式的测量误差传递特性以及状态模型建立的难易程度。最后对两种模式的跟踪精度进行了仿真实验,仿真结果表明,相比于前一种模式,后一种模式的跟踪性能获得了明显的改善。研究结果能为星载雷达对弹道目标跟踪模式的选择提供设计依据。Aiming at the problem of tracking mode selection of ballistic targets by using a space-borne radar, on the basis of establishment of a coordinate system required by space-borne radar for tracking orbital tar gets, two modes are designed, the one is that the conversion is performed firstly, then the absolute state of too-tion is tracked~ the other is that the relative state of motion is tracked firstly, then the coordinate conversion is performed. The analysis of constraints for the two tracking modes is discussed, which includes the characteris-tics of measuring error transferring and the difficult for establishment of state modeling. Finally, a simulation experiment is made for the comparison of tracking accuracy of the two designed modes. The simulation resultsshow that, compared with the former mode, the latter mode can obtain a significant improvement in tracking performance. The research can provide the design basis for space-borne radar tracking ballistic target mode se- lection.
