Emissivity measurement study on wide aperture microwave radiator

摘要：

The comparison research of emissivity measurement methods is presentedIn This paper. Different from the computation and measurement of general plane absorbing material,the emissivity measurement of pyramid microwave blackbody need consider near field effect,scattering effect and influence coming from measurement system reflection. Hence the measurement modeling of the former can not work well at measuring the emissivity of the latter. To improve emissivity measurement methods,the BIRMM (namely authors address)and the VNIIFTRI (All Russia scientific research institute for physical technical and radio technical measurement) finished together an international comparison measurement on same sample. The measurement methods used by BIRMM and VNIIFTRI and data are presentedInfollowing sections.
