摘要
本文介绍了毫米波吸收材料功率反射系数ρ的一种新测量法——辐射计测量法.通过测量吸收材料的辐射温度,计算得出吸收材料的辐射系数ε,从而得出功率反射系数ρ=1—ε.最后分析了这种测量法的误差.
A new method, radiometer-measuring-method, is presented to measure the reflective coefficient p of a millimeter-wave absorber in this paper. A millimeter-wave radiometer is used to obtain the radiative temperature of a millimeter-wave absorber, and the radiative coefficient e equals the ratio of its radiative temperature to its physical temperature. The reflective coefficient is ρ=1-εs. Errors in p are analyzed at last.
