随着高空温度探测精度要求的日益提高，如何减小温度传感器测量误差已成为亟需解决的问题，而太阳辐射作为影响温度传感器探测性能的重要因素已成为该领域研究的热点。利用计算机仿真技术，引入太阳高度角、引线夹角2个影响因子，根据流体动力学模型模拟分析探空温度传感器从海平面上升到32 km高空时所受太阳辐射的影响，最终得到辐射误差与海拔高度的关系曲线族，仿真结果将为开展高空温度传感器误差分析提供基础依据，从而提高传感器测量准确度。

With the increasing attention focused on the measurement accuracy of the high altitude air temperature, it is necessary to research into the source of the radiosonde temperature sensor error. Solar radiation makes the most significant contribution to the error in upper air temperature measurement. A computational fluid dynamics( CFD) method is employed to study the errors induced by solar radiation and lead angles,from sea level to 32 km altitude. The results show that lead angle and solar incident angle are important factors that affect the errors. Simulation re-sults can be used as a reference for error correcting,which has a potential to improve the measuring accuracy.
