A New Technology Study on Overlapped Absorbed Peak of Infrared Hybrid Gas
基于吸收峰混叠的红外混合气体分析方法的研究

According to feature extraction of high order cumulant, a method is proposed to solve the quantitatively analyzing of five types of gas, where the primary and secondary absorbed peaks are seriously overlapped. The absorbed spectrogram is mapped to four-order cumulant space and detached from each other. A technique is presented based on support vector machine of regularization theory to construct multi-dimension model, and accuracy and iterated rate are improved in small scale samples. The result hints the referenced error is no more than 4% , and satisfied with outfield demands.
