防空导弹毁伤目标的性能不断增强,传统基于质点的空中目标模型不能很真实的体现目标各项性能,跟踪效果不理想。针对这个问题提出一种基于刚体的六自由度模型。这种模型不仅具有三维的位置信息,还有三维的姿态变化信息,并根据空中目标的特点简化计算。仿真结果显示,这种方法有更高的跟踪精度和稳定性,且不易丢失目标,并能更好的体现目标各方面状态。

Target damaging performance of air-defense missile is growing. Traditional model of air targets based on particle can not reflect various performances of target, tracking effect are not ideal. In order to solve the problem, a six degrees-of-freedom model based on body has been proposed. This model has not only 3D position information, but also 3D attitude change information, and simplified calculation was achieved based on characteristics of air targets. The simulation results show that this approach has higher tracking accuracy and stability, not apt to lose goals, can better reflect target state.
