摘　　要：在提出日凌干扰处理新模型的基础上,根据太阳视面与天线主瓣半功率点截面的相对运动关系,系统阐述了日凌时天线噪声温度的分析方法。把足以影响日凌干扰整个变化过程的特征量——天线噪声温度增量作为分析与研究的中心,从总体上把握日凌干扰过程,提出了日凌中心日期中心时刻的天线温度以及整个日凌过程中各日期各时刻的天线噪声温度增量变化的理论计算模型。A new model of dealing with solar radiating disturbance is put forward and a systematic explanation to the antenna noise temperature analysis in case of solar radiating disturbance is made. The increase of antenna's noise and temperature, as a key factor that can influence the whole process of solar radiating disturbance, is under thorough investigation in this study to obtain a panoramic view of the disturbing process. Besides, the theoretical models for the calculation of the antenna noise temperature at the very point of disturbance and those at different periods of the disturbance are put forward.
