Paper Abstract
Fourier transform infrared (FuR) spectrometer with its high radiometric reproducibility wavelength accuracy signal-to-noise ratio and spectral resolution has been established as an ideal tool for air pollutants detection in city. Because most pollutant gases exhibit significant absorptivities in infrared spectral regions FTIR system can measure their hyper-spectral absorption signatures analyze the composition and provide the concentration estimation. The flexibility of airborne FTIR system in combination with its great detectable distance makes it even more suitable for the detection of pollutant cloud. This paper focuses on the detection principle of airborne pollutants and concemed signal processing techniques such as the establishment of spectral database pro-processing and characteristic extraction identification and classification for spectral signals pollution evaluation simulation techniques and etc.
