毫米波迷彩隐身涂层发射率分布数值计算

推导得出了毫米波隐身涂层发射率随着目标表面真实温度以及几种典型环境发射率之间的关系；在此基础上，以地面为典型环境，将其发射率作为主色发射率，推导了三色毫米波迷彩发射率取值范围表达式，分三种情况讨论了三色毫米波迷彩发射率的取值范围，及其随着目标表面真实温度变化之间的关系。结果表明，在300~400 K温度范围内，迷彩主色发射率应与环境发射率相近（对于地面来说为g=0.935），配色发射率取值随着目标表面真实温度的变化单调变化；且它们的取值范围相同，并随着目标表面真实温度的升高而减少。所得到的结论对毫米波隐身迷彩涂层色斑发射率分布设计具有指导意义。

Numerical calculation of millimeter wave pattern painting stealthy coat emissivity

The relationship between the emissivity of millimeter wave stealthy coat, the real temperature of target surface and some typical environment emissivity was calculated; based on that, the emissivity value range expression of three color millimeter wave stealthy coat was deduced with the typical environment emissivity. The relationship between the color block emissivity value ranges with the real temperature of target surface was discussed in three different cases. The result shows that in the 300-400 K, the main color emissivity value should be similar to the environmental emissivity(for the ground, g=0.935), the harmonize emissivity value changes monotonically with the target surface real temperature; they have the same value range, and decrease with the increase of the target surface real temperature. The conclusion plays a guiding role in designing the millimeter wave stealthy coat.
