Abstract: The present invention is not a method of directly calculating the rotational characteristics of a ball through frequency analysis of a received signal as in the prior arts, but a method of determining a final spin information by finding the spin information of the moving ball while approaching a ball trajectory predicted in terms of the trajectory of a moving ball using the position coordinate data of the ball to the trend data indicating the trend of the position coordinates of the moving ball. The present invention provides a method of finding the spin in terms of the trajectory of the moving ball, regardless of whether it is possible to check the frequency characteristics of the rotation of the ball from the signal reflected from the moving ball, and thus derives a fairly accurate and uniform spin calculation result.
