摘要
本文主要介绍天体辐射天线温度的两种定标形式,即天线后端温度定标和天线口面温度定标.还介绍用于天线口面温度定标和天体辐射温度定标的微波黑体噪声源的辐射特性及其应用等.
In this paper two methods of the calibration of the celestial emission antenna temperature that has been calibrated for both the temperature at the end of the antenna and at the aperture plane of the antenna are persented, emission characteristic and application of noise sources of the microwave blackbody is described which have been widely used to the calibration at the aperture plane of antenna and the calibration of celestial emission temperature.
