Quantitative Analysis of Infrared Spectra of Hazardous Clouds by Passive FTIS and the Limits of Detection with Atmospheric Model

利用 LOWTRAN所提供的大气模式 ,给出定量分析被动傅立叶变换红外光谱仪(FTIS)遥测污染云团红外光谱特征的方法。详细讨论了污染云团红外光谱的仿真结果和几种云团的被动 FTIS探测极限。结果表明 :它们是定量评估被动 FTIS探测性能和光谱鉴别器的重要工具。

The model of computer simulation for infrared spectra of hazardous clouds with the use of LOWTRAN is presented.The algorithm for quantitative analysis hazardous clouds of the limit detection by passive Fourier transform infrared spectrometer(FTIS) is given.The simulated results are discussed for several hazardous clouds with the U.S.Standard model.The detection limits of passive remote detection by FTIS for several important hazardous clouds are analyses in LOWTRAN.The simulated spectra will be useful in quantitative assessing performance of FTIS sensors and spectral discriminator.
