摘　　要：机载光电跟踪系统主要用来探测、定位和跟踪地面目标,其作用距离是评价系统性能的一个非常重要的技术指标。通过对机载光电跟踪系统结构和原理进行深入的研究,对影响机载光电跟踪系统截获目标的目标大小、目标背景对比度、大气衰减特性、光电传感器性能等因素进行了分析,建立了估算机载光电跟踪系统作用距离的数学模型,最后对某型机载光电跟踪系统作用距离进行了仿真计算。Airborne electro -optical tracking systems are designed to automatically detect, locate, and track ground targets. Its detection performance range is very important in evaluating the features of airborne electro -optical tracking system. By a generic method for predicting the detection performance the principle of electro - optical tracking system is presented. The performance predictor includes models of target,background, atmospheric attenuation, electro - optical sensor of the airborne electro - optical tracking system, and it also includes algorithms for target detection. Simple performance modes for electro -optical sensor systems predict a sensor＇s ability to detect a target with a certain size and contrast as a function of distance. The presented genetic model considers these effects by a direct empirical approach, and determines the ability to detect specific targets in a non- cluttered environment.
