  • DETERMINATION OF SPIN PARAMETERS OF A SPORTS BALL
    Publication number: 20090075744
    Abstract: A method of determining spin parameters of a spot ball, such as spin axis and rotation velocity of a golf ball. The spin axis is determined solely from the trajectory of the flying ball, and the rotational velocity is determined from a frequency analysis of a signal provided by a radar, which signal comprises spectrum traces positioned equidistantly in frequency, which frequency distance relates to the spin velocity.
