METHOD FOR ACOUSTIC SIGNAL DETECTION USING SIGNAL MODEL AND APPARATUS THEREFOR

摘要

The present invention relates to a method and an apparatus for acoustic signal detection using a signal model. The method for acoustic signal detection using a signal model is performed by an apparatus for detecting a sound signal generated from a firearm, and the method includes the steps of: extracting a feature point when variation of a size of a projectile shock wave from a sample of the projectile shock wave is equal to or greater than a preset reference value; generating a signal model of the projectile shock wave based on the extracted feature point; receiving a sound signal including the projectile shock wave generated from the firearm; and detecting the projectile shock wave based on the comparison of a feature point of the generated signal model with a feature point of the sound signal generated from the firearm. According to the present invention, a desired sound signal may be accurately detected in an environment with noises.
