摘　　要：微波辐射计是气象卫星对地观测微波遥感重要仪器之一,通过接收被观测场景辐射的微波能量来探测目标的特性。而微波辐射定标是微波遥感探测资料定量化应用的基础。以目前气象卫星的微波辐射计以此为例,对微波辐射计的定标方法进行了概述,并对微波辐射计的定标误差进行了分析和估算。The microwave radiometer is one of the most important microwave remote sensors; it can detect the features of the target through receiving the microwave radiation energy of the observation scene. And the microwave radiation calibration is the base of the quantitative application of the microwave detection material. This paper takes the microwave radiometer of the present meteorological satellite as the example, summaries the radiation calibration of the microwave radiometer, and analyzes and estimates the calibration error analysis of the microwave radiometer.
