Abstract

A golf ball performance evaluation system includes an initial properties analyzing unit for measuring and analyzing kinetic properties of a golf ball immediately after the golf ball is hit by a golf club, and an in-flight properties analyzing unit for measuring and analyzing kinetic properties of the golf ball hit by the golf club during a flight on its trajectory.

Claims

1. A golf ball performance evaluation system comprising:

an initial properties analyzing unit for measuring and analyzing kinetic properties of a golf ball immediately after the golf ball is hit by a golf club; and

an in-flight properties analyzing unit for measuring and analyzing kinetic properties of the golf ball hit by the golf club during a flight on its trajectory.

2. The golf ball performance evaluation system according to claim 1, wherein the in-flight properties analyzing unit comprises a radar transmitter-receiver unit that transmits radio waves towards the golf ball and receives radio waves that are reflected back by the golf ball.

3. The golf ball performance evaluation system according to claim 1, further comprising an elevation angle measuring unit for measuring an elevation angle of a trajectory drawn by the golf ball flying after having been hit by the golf club.

4. The golf ball performance evaluation system according to claim 2, further comprising an elevation angle measuring unit for measuring an elevation angle of a trajectory drawn by the golf ball flying after having been hit by the golf club.
