摘要
为实现动能拦截器导引头对弹道导弹目标的稳定跟踪,构建导弹自由段的运动模型和动能拦截器自身的误差分析模型,并通过相对运动关系推导导引头目标跟踪系统的非线性滤波模型。鉴于末段拦截的高时效性和快速收敛的滤波要求,采用基于在线协方差修正的扩展卡尔曼滤波对导引头目标跟踪系统的非线性模型进行仿真研究,仿真结果验证了导引头目标跟踪非线性模型的准确性和滤波算法的有效性。
The kinetic modeling of free-trajectory ballistic missile and the error modeling of kinetic kill vehicle have been worked out to realize stable and accurate target tracking. From the relative motion relationship, the nonlinear filtering model of the seeker target tracking system has been deduced. The extended Kalman filter with online modified covariance has been used to get the quick filtering and fast convergence. The result of the simulation has verified the accuracy of the nonlinear tracking modeling and the effectiveness of the MVEKF algorithm.
