Moving Body Rotation Speed Measurement Device

摘要

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.

主权项

1. A moving body rotation speed measurement device, comprising:
an antenna having directivity, that transmits a transmission wave to a spherical moving body based on a supplied transmission signal, and receives a reflection wave reflected at the moving body and generates a received signal; a Doppler sensor that supplies the transmission signal to the antenna, and generates a Doppler signal having a Doppler frequency based on the received signal; an input unit to which diameter information of the spherical body is input; a measurement processing unit that calculates the movement speed and the rotation speed of the moving body based on the Doppler signal and the diameter information; a display unit that displays display contents including the calculated movement speed and rotation speed; and a casing that retains at least the display unit.
