摘要： A velocity/distance detection system includes a transmitter and a receiver and detects a distance between the transmitter and the receiver. The transmitter transmits a composite frequency signal. The receiver includes a receiving unit that receives the composite frequency signal transmitted from the transmitter, an operating unit that performs an operation so that a difference in plural power estimate values or amplitude estimate values becomes target precision, a velocity estimating unit that estimates a velocity when the difference becomes the target precision as a velocity of the transmitter or the receiver, and a distance estimating unit that extracts each phase of the plural frequency signals when the difference becomes the target precision, calculates a propagation delay time of the composite frequency signal between the transmitter and the receiver based on each extracted phase, and estimates a distance between the transmitter and the receiver based on the calculated propagation delay time.
