Abstract
A single antenna has directionality, transmits a transmission wave toward a golf ball on the basis of a supplied transmission signal, receives a reflected wave that is reflected off the golf ball, and generates a reception signal. A Doppler sensor generates as time series data a Doppler signal having a Doppler frequency. A measurement processing unit calculates a movement direction of a mobile body on the basis of the correlation between the movement direction of the mobile body and the differential between the velocity of a mobile body for a reference time measurement obtained in advance and the velocity of the mobile body after a prescribed amount of time has elapsed from the reference time.
