红外系统迎头跟踪空中或掠海目标的作用距离分析与试验薛天柱（华北光电技术研究所北京１０００１５）为了获得尽可能远的迎头跟踪作用距离，必须使红外系统接收到尽可能多的目标辐射能量，如目标表面气动加热辐射，尾流与尾流环境加热辐射，以及目标周围气体选择性辐射等... Infrared system analysis and experiment on the distance of head tracking air or sea sweeping target Xue Tianzhu (North China Institute of Optics and Electronics, Beijing 100015) In order to obtain the tracking distance as far as possible, the infrared system must receive as much target radiation energy as possible, If the target surface aerodynamic heating radiation, wake and wake environment heating radiation, and the target gas selective radiation around ...
