发明名称 Golfing apparatus
摘要 A golfing apparatus for estimating the carry distance of a struck golf ball includes a doppler radar unit, a correlating circuit and a display. The doppler radar unit measures the doppler shift of the struck golf ball and a predetermined, empirically derived factor is used to correlate the measured doppler shift to an estimated carry distance for the ball. The display shows the estimated carry distance.
