| 摘 要： | "猫眼"目标回波功率是激光主动探测系统的重要指标,可用来评估光电装备"猫眼"效应的强弱,并为探测器的优化设计提供参考。依据所建立的斜入射条件下"猫眼"目标回波功率数学模型,仿真分析了入射角对"猫眼"目标回波功率的影响,利用搭建的激光主动探测系统对典型"猫眼"目标进行了实验研究,理论仿真结果与实验结果表明,激光在有限斜入射条件下,"猫眼"目标回波功率将随入射角的增大而迅速下降,并很快湮没于噪声之中。这为进一步研究基于"猫眼"效应的激光主动探测适用条件提供必要的实验依据。

| Abstract: | Retro-refleeted wave power of ＂cat-eye＂ target is an important index for active laser detection system,which can evaluate high or low ＂cat-eye＂ effect of photoelectricai device and provide reference for detector＇s optimal design.A mathematical model of oblique incident angle on retro-reflected wave power of ＂cat-eye＂ target is built.Effect of laser＇s incident angle on retro-reflected wave power of ＂cat-eye＂ target is simulated.Experimental research on typical ＂cat-eye＂ target is realized by using the active laser detection system.Theoretical simulation result and experimental result show that retro-refiected wave power will be rapidly decline with incident angle＇s increase in fnite oblique incident condition,which can provide experimental basis for research on applicable conditions of active laser detection system. |
