Abstract
A system for locating players on a field includes first and second directional scanning antennas located adjacent the field. A transponder carried by the players detects the radiation from each antenna and transmits timing signals. The timing signals are received at a central station and compared to reference timing signals synchronized with the scanning of the antennas to provide an indication of the angular position of each player from the scanning antenna locations. The actual field position of the players can then be computed. The system can also locate the position of a playing object, such as a ball.
