| Abstract: | It is know that a shooter may be located through the observation of the shock wave from the muzzle blast. A physical model describing this phenomenon is presented in this paper, which can be used to estimate the shooter location and bullet trajectory. The numerical results show that how to distribute omnidirectional microphones is extremely important to determine the detectable range of the object and ranging accuracy. In addition, it is fond that the present extended generalized inverse method is an effective tool to solve the model that consissts of non-liner equations. |
