Abstract:
Aiming at the large deviations of estimated localization of sound source by the five-element acoustic array passive acoustic positioning method,this paper proposed a model of seven-element acoustic array and a mathematical formula to solve the problem.Based on error analysis theory,the location performances of two acoustic arrays were compared in order to find the better method and the relationship between positioning deviation,azimuth,angle of pitch and delay time.Through computer simulation of one hundred random object sound source location,it showed that the seven-element acoustic array has the better performance of location.
