A Method Research on Orientation Estimation of Gas Signal Source Using Dual-Line Array

For application researches of the detection for the gas signal source, a method for orientation estimation of the gas signal source in the two-dimensional space and its algorithm are presented in the paper. In the method, a mode of dual-line gas sensor array is applied to sample the signals of the gas concentration in real time, and the time delay estimation, an approach of the signal processing, is used to establish an algorithm for performing the orientation estimation of the gas signal source. Furthermore, the simulations of the method are drawn, which indicates that the method has fine veracity and robustness for estimating the orientation of the gas signal source.
