Advances in digitized signal processing algorithms for remote infrared chemical sensing
Some digitized processing techniques developed for remote infrared vapor signal detecting, such as pattern classification, frequency-domain digital filtering and time-domain digital filtering, are introduced. The applications of linear discriminant, piecewise linear discriminant and artificial neural network on remote infrared chemical sensing are preliminarily discussed. The background subtraction, frequency-domain digital filtering and the apodization methods for digital filtering are briefly described. The principle and the usage of time-domain filtering are illustrated. An outlook on digitized signal processing algorithms for remote infrared chemical sensing is given.
