摘要
本文分析了遥感微波辐射计的逆向辐射噪声温度和口面定标源的亮度温度，建立了口面定标源的亮度温度模型。深入分析用口面定标方法反演微波辐射计的天线温度时过向辐射噪声对天线温度标定的影响。
The inverse radiation noise of a microwave radiometer for remote sensing is analysed in this paper. A model is used to determine the bright temperature of an aperture-calibration source. The effect of inverse radiation noise on antenna temperature calibration in the aperturecalibration method is expounded.
