摘　　要：大气风场和温度场是重要的大气基本参数,由于应用领域广泛,其探测技术在很多国家已发展成熟,中国对该探测技术的需求也日趋强烈。大气风场和温度场测量是利用高精度的光谱仪,通过测量大气中特征谱线的多普勒频移和展宽,来确定大气的温度分布场和风向风速场。星上定标技术是大气风场和温度场星载探测光谱仪进行高精度测量的基本保障。文中就几种重要的大气风场和温度场探测光谱仪的星上定标技术进行分析和总结,为大气风场和温度场探测技术发展提供参考,打下基础。The atmospheric wind fields and temperature fields are important atmospherical parameters.The atmospheric wind and temperature measurement technology was already developed in many nations for years,and there is increasingly demanded in China now.Atmospheric wind and temperature are measured by the spectrometers of high spectral resolution,which detects the Doppler line shift and expanding of the special spectrum line in the atmosphere.The in-flight calibration technology is critical for high resolution measurement of the atmospheric wind.Several typical atmospheric wind measurement spectrometers are reviewed,analyzed and summarized.The in-flight calibration technology used in these spectrometers is given.
