摘　　要：激光主动探测是利用光学系统的“猫眼效应”对敌方侦察设备进行探测识别的技术,其核心技术是利用回波精准地找到敌方光学探测器的位置,从而实施对探测器的干扰或其他措施。构建了激光主动探测中激光传输的基本模型,讨论了大气衰减、离焦量和入射角度等多种条件对激光主动探测的影响;基于激光主动探测的光电回波图像,以实际探测过程中的激光传输特性为基础,创造性地提出了回波功率、目标大小、目标形状3种判据,与传统目标检测算法相结合,实现了对敌探测设备的精确识别定位;通过实例检验,验证了该算法相较于传统算法具有更好的识别能力,且具有较强的通用性和一定的实战应用价值。Laser active detection is a technology to dect and identify enemy reconaissance equipment by using the"cat's eye fleet"of optical system.Its core technology is to pinpoint the location of enemy optical detector,so as to implement interference or other measures to the detector.The basic model of laser transmission in laser active detection is set up,and the influence of several conditions,such as atmospherie attenuation,defocusing amount and ineident angle,on laser active detection is discussed.Based on the photoeleetric echo image of laser active detection,as well as the laser transmission characteristics in actual detection process,the three criteria of echo power,target size and target shape are creatively proposed and combined with the traditional target detection algorithm,and the accurate identifcation and positioning o enemy detection equipment is realized.The testing via examples verifies that this algorithm has better recognition ability than the traditional algorithm does,and has strong universality and certain value in actual combat applications.
