A pre-processing algorithm for the detection of shotguns has been implemented using the General Cross-correlation (GCC) method. The relationship between Sound Pressure Level (SPL) and distance for different gunshot sounds are studied to determine whether the sound is loud enough to be detected as a gunshot at a certain distance range. The shotgun sound pattern received is made to correlate with a unique shotgun filter which is extracted from the muzzle blast pattern of a reference shotgun. In this paper, a brief description of detection approach is presented along with the corresponding simulation results. |
