TrackMan

The TrackMan is a radar system that uses Doppler technology to track and record 3D characteristics of a sports ball in motion.

TrackMan was created in 2003 by golfers and brothers Klaus (CEO) and Morten Eldrup-Jørgensen and radar engineer Fredrik Tuxen (CTO).

Television broadcasters also utilize it to display on-screen graphics such as the ball's trajectory as a golfer hits his or her tee shot.

[3] Major League Baseball uses Statcast, a system that uses cameras and radar to track and measure player and ball movements at all times.

PITCHf/x used high-speed cameras to measure the velocity of a baseball at 55 feet from home plate, where the ball may have already lost some speed.
