A Method for Locating Acoustic Sources of Multiple Explosion Points Based on Evidence Fusion

The acoustic signal characteristics of multiple projectile explosions were analyzed, and a set of fusional localization method for multiple explosion points of salvo projectiles which was suitable for practical measurement environments was studied. This method firstly theoretically analyzes the characteristics of multiple explosion acoustic waves and the chaotic signal timing and adhesion, a microphone is deployed around the area of the explosion point to be tested, and a data processing model based on evidence theory is established according to the wave arrival time measured by the microphone, a sample dataset of explosion point coordinates is established, and the target is checked and eliminated based on multiple pieces of evidence, the evidence mainly includes spatial consistency, energy consistency, completeness of wave arrival time and target quantity. The method was applied to a certain salvo projectile combat test, and the processing results are consistent with the post test results, verifying the reliability and correctness of the method proposed in this article.
