摘　　要：基于电波吸收、反射和散射特性对泡沫衰减遮蔽机理进行了探讨研究,对目标红外辐射在大气中的透过率进行了定量分析与计算。根据泡沫遮蔽状态的不同,分别对泡沫层和泡沫云两种干扰形式下目标红外辐射的透过率进行了定量计算,并利用MATLAB仿真工具进行了数值仿真,结果表明:泡沫相比大气对目标红外辐射的衰减作用明显,并且随着泡沫厚度的增加,目标红外辐射透过率逐渐减小,与实验测得的数值基本一致,进一步验证了模型的合理性。Based on the absorption, reflection and scattering characteristics of electromagnetic wave, attenuation shelter mechanism of foam was discussed and studied, transmission of infrared radiation of target in the atmosphere was calculated and analyzed quantitatively. According to the difference of foam shelter condition, transmission of infrared radiation of target for foam layer and foam clouds were calculated respectively. MATLAB simulation tool was used in the numerical simulation, which shows that foam has obvious effect compared to atmosphere on transmission infrared radiation of target. With the increase of foam thickness, the transmission of infrared radiation of target diminishes. It is inline with the measured experimental values, and the rationality of models is proved further.
