PROBLEM TO BE SOLVED: To provide a revolution speed measurement device for a moving body, which enables a user or the like to easily measure the revolution speed of the moving body, which is a sphere.SOLUTION: Diameter information of a sphere, which is a moving body, is input to an input section 20. Based on a Doppler signal and the diameter information, a measurement processing section 24 calculates the moving speed and revolution speed of the moving body. The measurement processing section 24 calculates the moving speed by using the maximum value of a peak value among the Doppler signals obtained continuously during a given measurement time, and also calculates a revolution speed by using the maximum value of a frequency width. A display section 18 displays a display content including the calculated moving speed and revolution speed. |
