摘　　要：探讨了泡沫通过散射、反射和吸收作用衰减电磁辐射的机理,分析了在理想条件及自然条件下红外热像仪对目标的发现和识别概率。以此为基础并采用朗伯—比尔定律,建立了泡沫衰减遮蔽条件下红外热像仪对目标的发现和识别概率的数学模型。利用Matlab仿真软件进行了数值计算,结论为:随着泡沫厚度的增加,红外热像仪对目标发现和识别的概率逐渐减小,与实验测得的值基本吻合。The foam can attenuate the electromagnetic radiation by scattering, reflection and absorption, this mechanism is discussed. The target discovery and identification probability of infrared thermal imager in the ideal and natural conditions are analyzed. Based on the conclusion and Lamber-Beer law, the mathematical model of the target discovery and identification probability of infrared thermal imager in the foam attenuation masking condition is established. The values are calculated by using Matlab simulation software. The conclusion shows that the target discovery and identification probability of infrared thermal imager are decreased, with increasing of foam thickness, and that is consistent with the experimental values.
