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

exact text as granted — not AI-modified
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.
