Method for measuring spin information of ball hit and moved
PCT designated stageWO2026116987A1Sport apparatusRadio wave reradiation/reflectionDigital dataSpin axis
The purpose of the present invention is to provide a method for measuring spin information of a ball hit and moved. When a ball used in sports such as golf is hit and moved while rotating, a reflected Doppler signal of a radar signal is received, and digital data of the received signal is acquired and analyzed. Accordingly, the spin axis of the moving ball is calculated in a new manner that cannot be predicted by conventional technology, thereby improving the accuracy of spin axis calculation.
