Abstract
A method for determining velocity of a target object comprises transmitting a propagating wave emitted from a wave transmitter and detecting a reflected wave reflected back by the target object by using a wave receiver, and determining of a phase angle difference between two alternating electrical signals respectively representing the transmitted wave departing the wave transmitter and the reflected wave arriving at the wave receiver, wherein the velocity of the target object is determined as a function of the time rate of change of the phase angle difference between the two alternating electrical signals.
