Abstract
Provided is a moving body rotation speed measurement device that makes it possible for a user or the like to easily measure the rotation speed of a spherical moving body. An input unit receives diameter information about a spherical moving body. A measurement processing unit calculates the movement speed and rotation speed of the moving body on the basis of a Doppler signal and the diameter information. The measurement processing unit calculates the movement speed using the maximum peak value of a Doppler signal obtained continuously over a predetermined measurement time and calculates the rotation speed using the maximum frequency width value of the Doppler signal. A display unit shows display content that includes the calculated movement speed and rotation speed.
