MOBILE BODY MEASUREMENT DEVICE AND MEASUREMENT METHOD

摘要

A single antenna (14) has directionality, transmits a transmission wave (W1) toward a golf ball (2) on the basis of a supplied transmission signal, receives a reflected wave (W2) that is reflected off a golf ball (2) and generates a reception signal. A Doppler sensor (22) generates as time series data a Doppler signal (Sd) having a Doppler frequency (Fd). A measurement processing unit (24) calculates a movement direction of a mobile body on the basis of the correlation between the movement direction of the mobile body and the difference between the speed of a mobile body for a reference time measured and obtained in advance and the speed of the mobile body after a prescribed amount of time has elapsed from the reference time.
