BALL TRAJECTORY CALCULATION METHOD USING SENSED RADAR DATA RELATING TO HIT BALL, AND RADAR SENSING DEVICE USING SAME

WIPO Patent Application WO/2023/048459

A1

The present invention relates to a radar sensing device for sensing a ball that has been hit and is moving, and the purpose of the present invention is to provide a ball trajectory calculation method using sensed radar data relating to a hit ball, and a radar sensing device using same, the method enabling a robust ball movement trajectory calculation despite radar signal distortion or phase jitter caused by interference between a person and a club or curvature on the surface of the ball. To this end, a ball trajectory calculation method of a radar sensing device for a hit ball, according to an embodiment of the present invention, comprises the steps of: collecting sensed radar data; and determining the validity of a trajectory by using the sensed radar data collected during a period preset as an initial movement period of the ball, and calculating a ball movement trajectory using a physics engine, on the basis of the result of the determination.
