随着科学技术迅猛发展,光电技术广泛运用于军事侦察、导航、搜索、跟踪、识别、火控瞄准和导弹,其中红外探测是一项比较成熟的光电技术。基于红外探测机理,从作用距离和目标探测概率两方面对红外接收系统进行分析。红外对抗是用来抑制、干扰、削弱、破坏红外系统的正常工作,干扰条件下红外接收设备探测概率将大大降低,文章建立了红外有源干扰和红外无源干扰条件下红外接收系统探测概率模型,对分析红外探测系统干扰情况下效能有一定的现实意思。
With the rapid development of science and technology, photoelectric technology is widely used in military reconnaissance, navigation, search, tracking, identification, fire control aiming and missiles, of which infrared detection is a relatively mature optoelectronic technology. Based on the infrared detection mechanism, the infrared receiving system is analyzed from the distance of action and the target detection probability. Infrared confrontation is used to suppress, disturb, weaken and destroy the normal operation of the infrared system, and the detection probability of the infrared receiving device under the interference condition will be greatly reduced. The detection probability model of the infrared receiving system under the condition of the infrared active interference and the infrared passive interference is established , There is some realistic meaning to analyze the performance under the interference of infrared detection system.
