摘　　要：采用傅里叶变换红外光谱法(FTIR)对大气中挥发性有机物(VOC)进行了被动遥测实验,提出了在复杂背景下定量遥测污染气体光谱的算法,讨论了被动FTIR的探测极限。这种测量技术和数据分析方法可在不预先测量背景光谱的情况下得到目标气体柱数密度和目标气体等效辐射温度。The paper expatiates the passive remote sensing experiment of VOC in atmosphere by FTIR spectrometry, a mode of simulated spectra for pollution gas in a eomplicated environment is proposed, and the detecting limit of passive FTIR remote sensing is discussed. Using this measurement technique and the data analysis method, the authors can obtain eolumn density and effective radiation temperature of target-gas that does not require a previously measured background spectrum.
