Abstract
A system is disclosed for detecting and locating missiles such as darts in a target having a plurality of discrete target areas in which each of the areas has a conductive surface which acts as an electromagnetic signal receiving antenna, and in which a plate is positioned on the back of the target which functions as an electromagnetic signal transmitting antenna. Each of the target areas are monitored for electromagnetic signals and the signals pass through a pin conductor to the monitoring equipment. When a dart is embedded in one of the areas, it also acts as an antenna and, thereby, increases the signal strength of that area to permit detection of the presence and location of the dart. The pin conductors and plate antenna at the back of the dart board substantially improve the discrimination and reliability of the system.
