ABSTRACT:
A system that accurately determines the location of the point of impact of a projectile, such as a golf ball, on a screen. A timer is provided that is activated when the projectile leaves a start point positioned at a known location. Upon impact of the projectile on the screen, a sound wave is produced that travels to a plurality of sound wave detectors. The system measures the time the sound wave travels to the plurality of sound wave detectors. These travel times are utilized to determine the point of impact of the projectile on the screen. The point of impact and flight travel time is used to determine the trajectory and velocity of the projectile. These parameters are then used to determine the distance the projectile would have traveled if unimpeded.
