远程运动点目标探测影响因素分析

Influence factors on detection of long range moving point target

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。

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.
