Abstract

In order to solve the problem of measuring the explosive position of projectile at the end of the ballistic zone, this paper proposes a method to measure the explosion position of projectile by using acoustic optic combined detection, researches the acoustic signal recognition and time extraction, and designs a compound eye photoelectric detection sensor with a large field of view, which provide a synchronous trigger collection projectile explosion sound signals. we establishes the calculation model of the explosion position of projectile based on the triangular three-element acoustic sensor array, uses the wavelet transform and the improved particle swarm optimization method to realize sound signal filtering and time extraction of projectile explosion. Based on the synchronous collection of the compound eye photoelectric detection sensor, we collect the acoustic signal of projectile explosion and identify the peak value and time of the projectile explosion, and gain the position of projectile explosion. It is verified that the design model and algorithm proposed in this paper are reasonable.
