In view of the limitations of the measuring method for measuring the falling point of the national range, this paper proposes a sound source localization algorithm based on time-delay estimation, and presents several factors that affect the positioning accuracy of the algorithm and several deployment methods of the sensor array The location errors of various distribution methods are simulated and the influences of the propagation speed error and the time difference measurement error on the positioning accuracy are analyzed by simulation. The results show that using acoustic positioning technology to measure the accuracy of the falling point coordinates can meet the requirements of the index. The rational positioning of the sensor array can improve the positioning accuracy.
