摘要
以上层大气中的气辉(极光)为被探测源,利用干涉成像光谱技术和电磁波的多普勒效应对上层大气风场进行测量,分析和计算了大气风场的速度和温度,并就被探测源和探测器之间的相对速度与其连线成任意角时的情形进行了讨论。采用计算机模拟,分析了大气风场的测量效果。
The interference image spectroscopy coupled with the Doppler effect of electrical and magnetic waves are employed to measure the natural airglow and auroral visible emission lines in the upper atmosphere. The velocity and temperature of the upper atmospheric wind field are analyzed and calculated. The relative velocity of the source to the detector with arbitrary angle to their link line is discussed. Computer simulation is employed for analyzing the effects of the measurement of the upper atmospheric wind field.
