PROBLEM TO BE SOLVED: To provide a person wearing speed measuring instrument capable of being worn by a person moving an object or the like to be a competition object and easily measuring an initial speed of the object, and a speed measuring method using the person wearing speed measuring instrument.SOLUTION: The person wearing speed measuring instrument includes an antenna for emitting a wave of a prescribed frequency to an object whose speed is measured and receiving a reflection wave of the wave from the object, and has a Doppler sensor for detecting and outputting a Doppler signal from the reflection wave, and wearing means 3 of the antenna on a person. The person wearing speed measuring instrument emits the wave toward the object, receives the reflection wave and detects the Doppler signal when the object is separated from an object located between a body part of the person brought into contact with the object or the person and the object. |
