1. An apparatus for analyzing a golf swing, comprising:
- a signal detecting unit including a Doppler radar sensor which radiates a transmission wave to a golf club and a golf ball and detects a reflected wave, in which a first reflected wave of the golf club and a second reflected wave of the golf ball are mixed, and detects a frequency deviation between the transmission wave and the mixed reflected wave and generates an output signal; and
a swing analysis information calculating unit configured to calculate a speed of the golf club and a speed of the golf ball by using the output signal,wherein;
the swing analysis information calculating unit calculates the speed of the golf ball based on a signal, which is obtained by converting the output signal into a frequency domain, and calculates the speed of the golf club based on a signal, which is generated from the output signal in a time domain, andwherein;
the swing analysis information calculating unit further includes a practice swing determining unit, which determines a swing as a hitting swing when the candidate speed of the golf ball has a predetermined value or more, and determines a swing as a practice swing when the candidate speed of the golf ball has less than the predetermined value, andwherein;
the practice swing determining unit differently applies the predetermined value based on the kind of golf club.

16. A method of analyzing a golf swing, comprising:
-
radiating a transmission wave to a golf club and a golf ball and detecting a reflected wave, in which a first reflected wave of the golf club and a second reflected wave of the golf ball are mixed, and detecting a frequency deviation between the transmission wave and the mixed reflected wave and generating an output signal; calculating a speed of the golf club based on a signal, which is generated from the output signal in a time domain; and calculating a speed of the golf ball hit by the golf club, based on a signal, which is obtained by converting the output signal into a frequency domain, and wherein;
the swing analysis information calculating unit further includes a practice swing determining unit, which determines a swing as a hitting swing when the candidate speed of the golf ball has a predetermined value or more, and determines a swing as a practice swing when the candidate speed of the golf ball has less than the predetermined value, andwherein;
the practice swing determining unit differently applies the predetermined value based on the kind of golf club. - View Dependent Claims (17, 18, 19, 20)
