| 摘 要： | 针对基于弹道切割模型的单平台仅测角射向估计效率低的问题,提出了一种基于映射矩阵的射向快速估计算法.首先,介绍了基于弹道切割模型的射向估计的基本原理,分析了该算法的不足.其次,以一个切割平面为基准,研究了其它切割平面与该基准平面的映射关系,进一步建立了映射矩阵.接下来,基于映射矩阵提出了射向估计的快速算法.蒙特卡罗仿真结果表明,该算法的射向估计精度与原算法基本相当,但计算效率提高了近6倍.

| Abstract: | Aiming at low efficiency of heading estimation on single platform, a fast heading estimation algorithm based on the mapping matrix is proposed. Firstly, the fundamental of the heading estimation based on a cutting plane is introduced, and the shortage of algorithm is analyzed. Secondly, the internal relation of each cutting plane is established, and the mapping algorithm among every cutting plane is structured. Thirdly, a fast heading estimation is proposed based on the mapping matrix. Monte-Carlo simulation results show that the efficiency of the heading estimation is improved in the condition of the same accuracy. |
