Golf ball locator
First Claim
1. A locator for locating a golf ball, the locator comprising:
- a radar;
a display;
a processor communicatively coupled to and configured to control the radar and the display; and
a memory communicatively coupled to the processor and having stored therein software instructions that when executed instruct the processor to;
cause the radar to send a radar pulse;
receive a radar return signal;
compare the radar return signal to a stored bifurcated radar signature characteristic of the golf ball, wherein the stored bifurcated radar signature comprises a first portion having a first radar reflectivity and a second portion having a second radar reflectivity, the first radar reflectivity contrasting substantially with the second radar reflectivity, and the stored bifurcated radar signature substantially distinguishes the golf ball from at least one other object;
calculate a position of the ball relative to the locator; and
display information concerning the position of the ball, including a narrative description of the position of the ball.

Abstract
A system and method for locating lost golf balls is described. In one embodiment, a plurality of small RFID chips are applied to or embedded in a ball. When the ball is to be located, a user uses a ball finder to receive RF signals from the RFID chips and locate the ball. The ball finder may have useful additional features such as overlaid maps to help and GIS data to help the user find the ball. In an alternative embodiment, a ball is prepared by applying a highly-reflective paint, such as a metallic paint, or a highly-absorbent paint such as a black iron ball paint, to create a characteristic radar signature for the ball. The ball finder may then be configured to locate the ball using the characteristic radar signature.

7. A computer-executable method of locating a golf ball comprising:
-
sending a radar pulse via a radar transceiver; receiving a radar return signal via the radar transceiver; constructing from the radar return signal a constructed radar signature for the golf ball; retrieving from a memory a stored characteristic radar signature of the golf ball, wherein the stored characteristic signature comprises a first portion having a first radar reflectivity and a second portion having a second radar reflectivity, the first radar reflectivity contrasting substantially with the second radar reflectivity, and the two radar reflectivities together providing a radar signature that substantially differentiates the golf ball from at least one other object; comparing the constructed radar signature to the stored characteristic radar signature to determine that they are substantially similar; calculating a position of the ball; and providing via a user interface a human-perceptible indication of a position of the ball, including a narrative description of the position of the ball. - View Dependent Claims (8, 9, 10, 11)

12. A tangible non-transitory computer-readable medium having stored thereon instructions operable to instruct a golf ball locator to:
-
send a radar pulse via a radar transceiver; receive a radar return signal via the radar transceiver; retrieve from a memory a stored characteristic radar signature of the golf ball, wherein the stored characteristic signature comprises a first portion having a first radar reflectivity and a second portion having a second radar reflectivity, the first radar reflectivity contrasting substantially with the second radar reflectivity, and the two radar reflectivities together provide a radar signature that substantially differentiates the golf ball from at least one other object; compare the constructed radar signature to the stored characteristic radar signature to determine that they are substantially similar; calculate a position of the ball; and provide via a user interface a human-perceptible indication of a position of the ball, including a narrative description of the position of the ball. - View Dependent Claims (13, 14, 15, 16)
