<p>A method is described to determine the position of one or more snipers when a listening station is located in the target area, and when the snipers are randomly located. The intelligent listening system can be located at a stationary or a mobile platform, consisting of a minimum of 2 microphones in the combination with a compass. The listening station registers shot sound from the sniper weapon and the shock wave from the projectile trajectory. These two signals are utilised to determine the north adjusted direction to the weapon and the shock wave. The position of the weapon is determined when utilising the speed of the projectile and the time difference between the shot sound from the weapon and the shock wave. The position is determined as the distance along the direction vector from the listening station and to the sniper weapon. Additionally the closest distance to the trajectory of the projectile is determined. A corresponding requirement can be satisfied in an open battlefield or for general surveillance when the time and the position of gunfire is of interest. Such information can be communicated over telephone or radio.</p> |
