摘要
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.
Abstract
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.
