“猫眼”目标的激光主动探测距离分析

Analysis of active laser detection distance for "cat's eye" target

激光对光电传感器主动探测的基本原理是基于光学系统的"猫眼"效应的。最大探测距离是探测系统的重要参数之一。对影响探测距离的几个重要因素如激光发射束散角、CCD灵敏度、大气能见度等进行了分析,给出了最大探测距离的数学模型,并在此基础上运用MATLAB进行了模拟仿真。分析结果表明,最大探测距离随激光发射束散角的减小、CCD灵敏度的提高而增大,随大气能见度的增强而增大。

The principle of the active laser detection for electro-optic sensor is based on the cat s eye effect of optical system.Distance is one of the most important parameter for active laser detection system.The mathematical model of maximal detection distance is given by the analysis of several factors including the angle of transmit laser beam,CCD sensitivity and atmospheric visibility,which are the main factors affecting the maximal detection distance.The analysis results show that the maximal detection distan...
