远程运动点目标探测影响因素分析

摘要

Many factors can affect long range detection of infrared system,such as the characteristics of the moving point target,background radiation,near field optical radiation,the performance of detector.Starting from the basic prin-ciple of point target detection,taking detecting the extraatmospheric moving target under deep space for example,esti-mation model of infrared detection range of long range target is established.Some influence factors on detection range are analyzed,which can provide a theoretical reference for design of long range infrared system.%红外系统实现远程探测，其影响因素很多，如运动点目标的特性，背景辐射，近场光学辐射，探测器的性能特性。本文从点源目标探测基本原理出发，以深空背景条件下探测大气层外的目标物为例，建立远程目标红外探测距离估算模型，分析了影响探测距离的相关因素，为远程红外系统的指标设计提供理论参考。
