摘　　要：21世纪后，临近空间飞行器成为各国研究的热点，准确的临近空间大气参数是研究临近空间飞行器的基础；为了获得临近空间高精度大气温度数据，提出了基于火箭探空仪的临近空间大气温度修正方法；通过分析某型火箭探空仪特殊机构及安装方式，提出了影响大气温度探测的4种因素：传感器滞后效应、气动加热、云层及地面反射的太阳辐射和测量电流的焦耳热效应，根据对4种影响因素的分析结果提出了相应的修正方法；为了提高温度数据的计算精度，根据气压、温度的相互影响关系提出了气压、温度迭代计算方法；目前，基于该修正方法的大气探测数据处理系统已经成功进行多次试验任务；试验结果表明，基于此方法可以获得20～60km高度范围内高精度的大气温度数据。In the 21st century, near space vehicle has become a hot research area. The accurate atmospheric parameters is the foundation of researching the near space vehicle. In order to get high--accuracy data of the atmospheric temperature, put forward the correction method about near space atmospheric temperature. Through the analysis of special institutions and installation method about a certain type of rocket radiosonde , put forward four kinds of factors, sensor lag effect, aerodynamic heating, solar radiation of cloud and ground reflection, joule heating effect, and propose correction methods of the four kinds of factors. In order to improve the calculation accuracy of temperature data, the iterative calculation method of pressure and temperature is proposed. The atmospheric data processing system based on the correction method has completed many test tasks. The test results show that the method can get high-- accuracy atmospheric temperature data of 20 km -60 km high precision.
