Abstract
A sensor is provided for measuring the speed of a moving sport object, for example, from a gun, bow or other implement, such as a bullet or paint ball or arrow. The sensor is operable over a short range and is preferably mounted in close proximity to the path of the moving object preferably utilizes CW Doppler radar of a microwave radio frequency. In use, the unit is situated so as to place a transmit/receive antenna close to or in the line of motion of the object. Such an antenna, so positioned, may be separated from the unit and connected through a transmission line. The remote display/annunciator can also or in the alternative be separated and located remote from the transmitter/receiver and connected by a cable or a wireless link. The sensor is useful for other speed measurements in sports applications, such as for measurement of bat speed, golf club head speed or the speed of another racket, club or bat type implement, or to measure punch or kick speed in martial arts.
