Abstract: This paper presents statistical approach in detection of the wave front of an acoustic blast wave in air. Detection of the wave front is significant in many areas where is necessary to perform location of such sources. Detection of blast waves, which originate from small explosions, is performed at local distances where acoustic propagation is confined to the atmospheric boundary layer. Therefore, characteristic signatures of the small explosions are preserved and a statistical method in process of detection is possible to use.
Keywords: small explosion, detector, signature of small explosion.
