| 摘 要： | 建立了一种描述弹道导弹作圆锥形螺旋机动的三维耦合运动数学模型.根据目标进行圆锥形螺旋机动的两种运动模式,得出了两种模式下具有相同形式的描述目标运动的状态方程,此运动状态方程是线性的且只与目标机动频率相关.进而给出了该状态方程的离散化形式,以及通过坐标转换关系,设计此类螺旋机动目标的跟踪滤波器的方法.最后通过导弹拦截实例仿真,验证了本文所提出的方法具有良好的目标跟踪效果.

| Abstract: | A three-dimensional coupling motion model is established for the Ballistic missiles, which actuate a conical spiral maneuvering. From two conical spiral maneuvering modes, a uniform state equation to describe the target motion is derived. The state equation is linear and only concerned with the target maneuver frequency. The discrete form of the state equation is proposed, and with a coordinate transformation technique a tracking filter is designed for the conical spiral maneuvering targets. Finally, simulation results show that the proposed model and design method has a good tracking performance for a conical spiral maneuvering ballistic missile. |
