摘　　要：大气风场是理解地球大气系统动力学、热力学特性的重要参数,是气象预报、空间环境监测、气候学研究等必须的基础数据。基于测风干涉仪的被动光学遥感是中高层大气风场测量的主要技术手段。多普勒差分干涉测风技术是一种新型行星大气风场探测技术,该技术通过对干涉图相位的反演来探测大气气辉辐射谱线的多普勒频移,从而实现大气风场探测。经过近二十年的时间,多普勒差分干涉仪的基础理论、干涉仪设计、系统研制工艺、数据处理与风速反演等方面取得了一系列研究成果。本文回顾了大气风场探测多普勒差分干涉仪技术的国内外研究进展,讨论其技术特点和应用潜力,为未来大气风场被动光学遥感探测技术发展和我国大气风场探测领域任务规划提供参考。Atmospheric wind field is an important parameter to understand the dynamics and thermodynamic characteristics of the Earth′s atmospheric system,and it is the basic data for weather forecasting,space environment monitoring,and climatology research.Passive optical remote sensing based on Optical interferometer is the main technical means of wind field measurement in the middle and upper atmosphere.In the 1960s,foreign research institutions began to use optical interferometers to detect upper atmospheric wind fields.and carried out the experimental research on interferometer payload technology simultaneously,and successively developed a series of representative scientific instruments and satellite payloads based on the Fabry-Pérot interferometer and the Wide Angle Michelson interferometer.In 2006,the ENGLERT C R research team of the U.S.Naval Research Laboratory proposed a new planetary atmospheric wind detection technology,called Doppler Asymmetric Spatial Heterodyne wind measurement technology,this technology detects the Doppler frequency shift of the atmospheric airglow spectrum by inverting the phase of the interferogram,thereby realizing the detection of the atmospheric wind field.Compared with the Fabry-Perot interferometer and the Wide-Angle Michelson interferometer,the Doppler Asymmetric Spatial Heterodyne interferometer has the following advantages:1)Two-beam equivalent thickness spatial modulation interference,which relaxes the requirements for the optical index of the element;2)Interferometer does not need Step-by-step scanning;3)Wind speed inversion is based on the Fourier transform relationship between interferogram and spectrogram,so it does not need extremely narrow bandwidth(<1 nm)filters to separate single-line spectra;4)Synchronous calibration can be achieved,the standard spectral line of the calibration light source and the target spectral line of the detection source are simultaneously introduced into the interferometer system to monitor the state change of the interferometer in real time,ther
