Abstract
The system for determining the carry and/or lateral deviation and/or flight time of a driven golf ball uses a grid of geophones to sense the time of impact of a driven golf ball. The geophones are buried in the ground so that the impact is sensed via sound waves travelling through the ground. A computer receives a signal from each sensor indicating an impact and determines the time at which the impact was sensed by each sensor and screens out all but the six shortest times of impact. This information is then used to mathematically calculate the point of impact within a square of geophones corresponding to the recorded times. A plot of the flight path of the golf ball can be displayed on a display monitor based upon the carry and the flight time. The calculated flight time and carry are compared with a known standard to determine conformance with the standard.
