1.27μm气辉的星载成像干涉仪风温探测技术
|
摘要
全球大气风场温度场探测具有重要的学术意义及广泛的应用前景。O_2分子的红外大气带(a~1Δ_g←X~3∑_g)在1.27μm波段的气辉具有相对较强的辐射以及相对较弱的自吸收,是实现较低空域的大气风场和温度场探测的最佳目标源之一。通过O_2临边辐射光谱特性分析确定了两组共6条最佳目标谱线,论证了这些谱线对风温探测的空间覆盖能力,探讨了谱线的分离选取技术方案,并借鉴MIMI仪器设计参数,采用Michelson干涉仪进行了正演数值仿真,得到临边观测图像。数值模型结果分析表明,以O_2 1.27μm波段的气辉辐射为探测源的Michelson干涉成像仪可以实现45～90 km
The observation of global wind and temperature is of great academic significance and wide application prospects.The infrared atmosphere of the O_2 molecule (a~1Δ_g←X~3∑_g) has a relatively strong radiation and a relatively weak self-absorption in the 1.27 μm band,and is one of the best target sources for atmospheric wind and temperature observation in the lower airspace. Therefore,two groups of lines which containing six best target lines are determined by O_2 limb viewing radiation spectrum characteristics,and the spatial coverage ability of these lines for wind and temperature observation is demonstrated. The technical scheme of separation and selection of lines is discussed. The forward simulation is performed by Michelson interferometer with the design parameters of MIMI,and the observation images of the limb viewing are obtained.The results of the numerical model show that the Michelson interferometer can detect the air wind field and temperature field of 45～90 km by using the Michelson interferometer with the gas glow radiation of the O_2 molecule at 1.27 μm band as the detection source.
