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 characteristics of absorption, reflection and scattering of radio waves, the mechanism of bubble attenuation is studied. The transmittance of target infrared radiation in the atmosphere is quantitatively analyzed and calculated. According to the different states of foam masks, the transmissivity of target infrared radiation under two kinds of interferences of foam layer and foam cloud were calculated respectively. The numerical simulations were carried out by using MATLAB simulation tool. The results show that the foam’s permeability to the target The attenuation of infrared radiation is obvious, and with the increase of foam thickness, the transmittance of target infrared radiation decreases gradually, which is basically consistent with the experimental data to further verify the rationality of the model.
