光电侦察阵列对空目标定位算法研究

 为扩大重点区域防御的侦察范围及对来袭目标的定位，在双单元交互测量定位算法的基础上，利用相邻阵列单元接力测量，由中心处理单元完成被动测距、坐标转换与数据融合，提出了一种基于阵列式光电侦察系统对空目标定位算法，建立m×n光电侦察阵列对空目标定位算法数学模型。通过MATLAB完成了2×2阵列单元对单目标定位仿真验证与误差分析。结果表明，该算法实时输出了目标三维航迹数据，实现了光电侦察阵列对空目标的定位，与理论真值相比，平均定位误差绝对值小于7 m。

Algorithm research of elelctro-optical reconnaissance array position on air target

For expanding the scope of the key area defense reconnaissance and positioning the incoming target, on the basis of two-unit interactive measurement positioning algorithm, the relay measurement of the adjacent array units and passive measurement, coordinate transformation, data fusion were accomplished by the central processing unit. An algorithm based on array of electro-optics reconnaissance positioning system on air targeting was proposed. A model of an m×n electro-optics reconnaissance array position on air target was derived, and the single target positioning simulation, verification and error analysis of 2×2 array element were accomplished with the help of MATLAB. Simulation results show that this algorithm can output the real-time data of the three-dimensional track and realize the positioning of the on air target. Compared with the theory of truth value, the absolute value of the average positioning error is less than 7 m.
