摘要
对激光探测技术的目标识别及定位方法进行研究.根据近场目标激光反射方程,结合典型的弹目交会条件,从理论上给出了坦克的激光反射特性;分析了激光探测的主要干扰,提出了判别反射脉冲幅度和脉冲个数的信号识别准则;采用统计分析方法,建立了坦克激光信号幅度直方图.在此基础上,结合探测概率制定幅度门限,根据定位要求及目标尺寸,分析了脉冲个数门限的确定方法.仿真结果表明,所设计的探测识别系统能有效判别坦克目标,并能对目标进行定位,实现对坦克顶装甲的精确打击.
Target identification and orientation are studied applying laser detection technique. Based on laser reflection equation of close field target and combined with typical meeting condition between missile and target, simulation curves of a tank＇s laser reflection characteristics are given theoretically. Main disturbances of laser detection are analyzed. The identification rules are put forward that distinguish the amplitude of reflected pulse and pulse number. Statistic analysis is adopted to set up histogram of laser signal of a tank. Then the amplitude threshold is established combined with detection probability. The method of ascertaining pulse number threshold is analyzed according to orientation requirement and target size. Simulation results indicated that the detection ＆ identification system can distinguish tank target effectively and orientate it, so as to realize hitting at a tank＇s top armour accurately.
