This paper makes use of the feature that the supersonic projectile will generate shock signals when flying, a system composed of 5 acoustic sensor arrays is constructed to detect the orientation and distance of the shock wave, and to determine the location of the terrorists hiding. A new method to determine the location of terrorists is established in the model. This model does not require projectile coefficient calibration, which solves a big problem in the development of the system.
