| 摘 要： | 本文研究适用于综合火力／飞行控制系统要求的机动目标状态估计的算法问题。通过选取直角坐标及伪测量量构成扩展Ｋａｌｍａｎ滤波。在此基础上，提出采用距离通道冗余滤波以提高距离通道的滤波精度，同时，得到了改善其它估计量精度的一种算法。通过综合火力／飞行控制系统的ＭｏｎｔｅＣａｒｌｏ仿真表明，该算法具有很好的性能。

| Abstract: | A maneuvering target state esitmating algorithm for Intergrated Fire /Flight Control (IFFC) is explored in this paper. This algorithm is an extended Kalman filter which adopts the Cartesian coordinates and pseudomeasurements.In addition,by employing accurate range and range rate redundant filter, the estimating accurancy obtained in Cartesian filter is greatly improved. The Monte Carlo simulation of the IFFC system shows that this algorithm has a satisfactory performance. |
