1. A golfing apparatus for determining the carry distance of a golf ball which a golfer has struck, said golfing apparatus comprising:
- (a) a speed measuring mechanism which has a boresight and which measures a component of the speed of the golf ball, said speed measuring mechanism being aimed at the golf ball while in flight, wherein said boresight of said speed measuring mechanism is disposed at angle in the range of zero degrees to twenty five degrees with respect to level ground; and
(b) correlating means for correlating said measured component of the speed of the golf ball with an empirically derived factor for use in determining the estimated carry distance of the golf ball, said correlating means being electrically coupled to said speed measuring mechanism.

Abstract
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.

7. A golfing apparatus for estimating the carry distance of a struck golf ball, said golfing apparatus comprising:
-
(a) a speed measuring mechanism having a boresight disposed at an angle in the range of zero degrees to twenty five degrees with respect to level ground wherein said speed measuring mechanism measures the speed of the struck golf ball; (b) a storage device holding an empirically derived factor, said empirically derived factor relating a speed of a previously struck golf ball as measured by the speed measuring mechanism to an observed carry distance of the previously struck golf ball; (c) a circuit coupled to said speed measuring mechanism and to said storage device whereby said circuit correlates the measured speed of the struck golf ball with the empirically derived factor, thereby producing an estimated carry distance for the struck golf ball. - View Dependent Claims (8, 9, 10, 11)

19. A method of obtaining a predetermined factor for estimating the carry distance of a struck golf ball, said method comprising the steps of:
-
(a) orienting a Doppler radar in an anticipated direction of the struck golf ball, (b) measuring a Doppler shift from the struck golf ball, (c) observing the actual carry distance of the struck golf ball, and (d) correlating the measured Doppler shift to the observed actual carry distance said correlation constituting the predetermined factor. - View Dependent Claims (20, 21)

22. A method of estimating tile carry distance of a struck golf ball, said method comprising the steps of:
-
(a) orienting a Doppler radar in an anticipated direction of the struck golf ball, (b) measuring a Doppler shift from the struck golf ball, and (c) correlating the measured Doppler shift to an estimated carry distance of the struck golf ball using a predetermined factor, said predetermined factor relating the measured Doppler shift to an observed carry distance of a previously struck golf ball.
