摘要
针对弹道导弹预警系统中的弹道实时估计难题,提出了一种新的卫星与雷达测量数据的加权快速融合方法,它是一种递推式计算方法,对有效测元进行逐个融合计算,可以提高估计精度。在此基础上,探讨了一种基于匹配多项式最小二乘滤波的雷达数据实时处理方法,该算法能有效的降低截断误差。给出了应用这两种方法的具体步骤,理论分析和仿真计算结果表明了算法的有效性。
To study the difficult problem of orbit real-time in a space and ground early system of ballistic missile, this paper presents a new rapid fusion method using measuring data of satellite and radar, As a recursive algorithm with high accuracy, the method fuses available measurement one by one, And based on the matching polynomial least square filter, a real-time algorithm deal with radar measuring data is presented. The efficiency of this method has been proved by theoretical analysis and the results of simulation.
