红外成像制导及其目标背景特性分析

IR imaging guidance and analysis of targets background characte ristic

结合对目标和背景的红外特性研究,阐述了在复杂背景条件下防空导弹对目标的红外成像寻的制导的组成和原理。详细分析了地面杂散背景的辐射和散射特征。综合分析了军用飞机被防空导弹攻击时的红外辐射特性。其分析结果对研究防空导弹红外成像导引头如何从复杂背景中将目标的典型特征信息提取出来并进行有效的识别具有重要的参考意义。

Combining the IR imaging characteristic research of target and its backgrounds, the constitute and principle for the IR imaging homing guidance system of the air-defence missile targets in clutter back-grounds is introduced. The IR radiation and diffusion characteristic of ground background are analyzed in detail. The IR radiation characteristic of the military plane that will be attacked by an air-defence missile is discussed comprehensively. Conclusions have an important reference meening for extracting the typical feature information of target in clutter background and efficient target recognition for air defense missile IR imaging seeker.
