| 摘 要： | 应用卫星短弧定轨理论,根据导弹运动特性建立被动段弹道动力学模型来约束其运动,研究了基于动力学约束的实时弹道滑动处理方法,能有效地提高弹道的定轨精度和稳定性。同时通过设计合理的累积窗口和滑动窗口宽度,可实现弹道处理近实时的快速计算。仿真结果表明,将该方法用于被动段实时弹道处理,其速度精度可提高1～2个量级,明显地克服了滤波定轨的收敛时间较长和单点定位精度较差的不足。

| Abstract: | To improve the precision and stability of ballistic determination,short-arc determination used on satellite is improved.According to the motion characteristics of missiles,a realtime ballistic sliding processing method based on dynamic constraints is studied by building the dynamic model of passive phase trajectory.Meanwhile,realtime fast computation on ballistic processing could be realized by designing reasonable widths of accumulating window and sliding window.Simulation results show that the ballistic r... |
