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εg=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。
The relationship between the emissivity of the millimeter-wave stealth coating and the real temperature of the target surface and several typical environmental emissivities were deduced. Based on this, taking the ground as the typical environment, the emissivity of the millimeter-wave stealth coating was taken as the dominant color emissivity, The expression of the value range of the three-color millimeter-wave camouflage emissivity is deduced. The range of the value of the three-color millimeter wave emissivity and its relationship with the real temperature change of the target surface are discussed in three cases. The results show that the main emissivity of the camouflage should be similar to the environmental emissivity (εg = 0.935 for the surface) in the temperature range of 300-400 K, and the value of the color emissivity changes monotonously with the change of the real surface temperature. And they have the same range of values and decrease as the true temperature of the target surface increases. The conclusion obtained is of guiding significance for the design of the emissivity distribution of millimeter-wave stealth camouflage coating.
