Abstract(in English) | This paper discribes the method for estimating a direction of infrasound arrival by a microphone array. It is difficult to estimate the arrival direction using MUSIC method without spatial smoothing in complex environment generated by coherent waves. For solving the problem, the method has been presented to estimate the arrival direction using spatial smoothing method that has uniform weight. In order to obtain a sharp peak value, we propose a method to determine a optimal weight of spatial smoothing method by the genetic algorithm and present some results of simulation on estimating the arrival direction. |
