Golf ball having at least one radar detectable mark

Abstract

A golf ball is disclosed herein that includes at least one radar detectable mark such that a projected pattern is formed when the at least one radar detectable mark is radially projected onto an outer surface of the golf ball. The projected pattern can have a first wave profile mapped along a path defined by a first spherical arc on the outer surface of the golf ball. The projected pattern can comprise at least one first crest and at least one first trough. The projected pattern can have a periodic function selected from: a sine wave, a sawtooth wave, a triangle wave, or a square wave.

What is claimed is:

 (i) a periodic function; 
 (ii) a wave profile; 
 (iii) an infinite sum of trigonometric functions; or 
 (iv) a combination of multiple wave forms. 
   
     
     
         2 . The golf ball according to  claim 1 , wherein the first and second profiles are defined by a periodic function. 
     
     
         3 . The golf ball according to  claim 1 , wherein the first and second profiles are defined by a wave profile, and the wave profile is at least one of: a sine wave, a sawtooth wave, a triangle wave, or a square wave. 
     
     
         4 . The golf ball according to  claim 1 , wherein the first and second profiles are defined by an infinite sum of trigonometric functions. 
     
     
         5 . The golf ball according to  claim 1 , wherein the first and second profiles are defined by a combination of multiple wave forms. 
     
     
         6 . The golf ball according to  claim 1 , wherein the projected pattern has a wave angular extent of at least 45 degrees. 
     
     
         7 . The golf ball according to  claim 6 , wherein the wave angular extent is 240 degrees-300 degrees. 
     
     
         8 . The golf ball according to  claim 1 , wherein the projected pattern extends for at least 1.0 period and less than 5.0 periods. 
     
     
         9 . The golf ball according to  claim 1 , wherein an amplitude of the first profile and the second profile is less than 40% of a diameter of at least one of: the golf ball, a cased core of the golf ball, or a sub-assembly of the golf ball. 
     
     
         10 . The golf ball according to  claim 1 , wherein the first and second profiles are defined as continuous, uninterrupted strips.
