Analysis of Shock Wave Signals and Calculation of Trajectory Vector in Acoustic Positioning System

Abstract:

Based on aerodynamics, this paper discussed the shock wave traits of ultrasonic bullet and studied the methods to calculate the position coordinate and ballistic trajectory vector in free sound field. Through experiments, the signals of shock wave from firing point and ballistic trajectory were decomposed and reconstructed, making use of wavelets analysis. The characteristic parameters were extracted to position the sound source and orientate the trajectory, based on the sensors array of right tetrahedron.
