摘要
在高光谱技术和大气微波辐射模型前提下,提出了在设计地基微波高光谱辐射计对晴空条件下大气状态量探测过程中应该同时注意通道数目和通道灵敏度等方面的因素,并结合信息熵理论给出这些因素对于大气温度反演前后的相关性分析。
A measurement of the atmosphere from the ground-based microwave radiometers with high spectral resolution contains a large amount of information about the atmosphere.This paper considered some critical factors,for example the channel number and channel sensitivity,during the design of high spectrum microwave radiometer for atmospheric state variable detection process.Based on hyperspectral technology and atmospheric microwave radiation model,the correlation analysis of these factors to the information content under the condition of clear sky atmospheric conditions was given.
