Abstract在卫星上对中间层顶区域的气辉辐射成像观测,对于全球大气波动的监测和研究具有重要的意义.利用TDICCD对O_2A(0-0)气辉进行成像观测,计算了曝光积分时间、信噪比和能达到的最高空间分辨率,分析了地球自转对空间分辨率的影响,在此基础上提出一种星载全球大气波动成像仪方案,该方案可以观测垂直波长大于10 km的大气波动,最高水平分辨率可以达到0.33 km.
Other AbstractSpace-based airglow imaging observation is significant for monitoring global atmospheric waves in the mesopause region.The Time Delay and Integration Charge Coupled Device(TDICCD) is used to capture images of O_2A(0-0) airglow.The required exposure time and the signal-to-noise ratio are calculated,and the latitude-dependent space resolutions are analyzed with a modulation transfer function.Due to the Earths rotation,for a circular orbit with a height of 700 km and an incline angle of 73°,the spatial resolution increases with in creasing latitudes,which is 5.7 km near the equator.Based on the above analysis,the instruments block diagram is also given.Results indicate that the space-based airglow imager can observe atmospheric waves with a vertical wavelength of approximately 10 km or longer and with the best horizontal spatial resolution of 0.33 km.
