ABSTRACT:
The present invention provides a method and apparatus for determining a desired parameter of the motion of an object. In one embodiment, the device can be used to calculate the estimated carry distance of a golf shot. The golfer uses a keypad to enter the golf club and the units of measure for the output display. A Doppler radar system is employed to illuminate the golf ball. A reflected return signal is detected and difference pulses are generated, having a frequency which is proportional to the velocity of the ball. The difference pulses are processed by a microprocessor to determine if the radar beam has "locked" onto the ball. If so, the microprocessor calculates the carry distance by relating the average period of the difference pulses to a projected carry distance through empirically determined data. The carry distance can be displayed on the device, on a remote display, and/or can be stored in memory for later recall or transmission to an external computer. The microprocessor can also be used to determine if the difference pulses it receives are related to the motion of a ball struck by the user of the apparatus by comparing incoming data to characteristic patterns of club-head movement and can be programmed to calculate and display the angle of trajectory and speed of the ball and club-head speed and swing tempo. Also, an acoustic trigger or electric eye can be used to activate the apparatus when the golf ball is struck.
