| 摘 要： | 首先分析了弹道特征的影响因素,然后利用微分几何的相关知识讨论了弹道特征的抽取问题,进而提出了用曲率/挠率-弧长作为参量提取弹道特征的方法,给出了理论分析和应用说明,最后利用仿真数据进行了验证。仿真结果表明,该方法能够准确反映出导弹的一些机动动作,如姿态调整及弹头抛撒等,在导弹目标识别中具有一定的应用价值。

| Abstract: | Following analyses of the influential requirements of trajectory characteristics,this paper discusses trajectory characteristics extraction based on the theory of differential geometry.Then,a method that utilizes three parameters,arc length,curvature and torsion,is proposed.Theoretical analysis and application instructions are given.The method is validated with simulation data and the results show that the method reveals certain maneuverable motion of missiles such as attitude adjustment and warhead projection and the results are valuable in the field of missile target recognition. |
