| 摘 要： | ;作为一种有效的大气污染气体遥感探测识别手段,傅里叶变换红外光谱仪已经得到越来越广泛的应用.当污染气体与背景存在温差时,红外光谱就能反映出污染气体的吸收或发射特征.目前,已有越来越多的人利用被动式傅里叶变换红外光谱仪进行大气污染气体的探测识别研究,而且也发展了许多由光谱提取目标信号的算法,但是这些方法大多是仅针对污染气体的定性研究的.利用仿真方法可以快速简便地计算出污染气体的浓度程长积,并可实现对遥感红外光谱的定量分析,且误差较小.

| Abstract: | As an effective method for remotely detecting the hazardous gas pollutants in atmosphere, the Fourier Transform Infrared(FTIR) spectroscopy has been used wider and wider.When there is temperature difference between the pollutant gas and the background,the absorption and emission characteristics of the pollutant gas can be revealed in infrared spectra.Up to date,more and more people have used the passive FTIR spectroscopy in their research on the detection of atmospheric pollutant gas and developed many algo... |
