摘　　要：针对现代战场诸如探照灯、照明弹、战场火光(多种面光源和点光源等)等强光光源对红外成像系统探测性能的影响,建立红外成像系统对面目标的识别性能和对点目标的探测性能估算的数学模型,并在VC6.0下实现对目标与背景温差、目标的识别距离等参数的计算,建立红外成像系统作用距离模型。最后,对红外成像系统分别受杂散光、强激光干扰以及硬损伤情况下的效果进行仿真,仿真结果可对实际红外成像系统受强光干扰效果做一借鉴,最后对干扰效果的提出了主观评价方法。Aiming at modern battlefield, in which searchlights, flares, fire and other intensive light source would affect the performance of infrared imaging system and its detection function, the study is to build a mathematical model evaluating infrared imaging system＇s recognition performance on the target and detection performance on the spot target, to realize the computing of parameters such as temperature difference between the target and background, recognition distance under VC 6.0, and to build action distance model of infrared imaging system. Finally, the study simulates the results of infrared imaging system under stray light, intensive light and physical damage. Simulation results would be a reference for the actual result of infrared imaging system performance under intensive light interference, at last, interference effects on subjective evaluation method is proposed.
