Abstract
A velocity determination system determines a three dimensional velocity of an object wherein the three dimensional velocity comprises a radial velocity and a transverse velocity. A velocity determination system receives a first signal from the object. The velocity determination system then receives a second signal from the object. The velocity determination system then correlates the first signal and the second signal. The velocity determination system determines the radial velocity based on a ratio of the correlation of the first signal and the second signal. The velocity determination system then determines a transverse velocity based on a ratio of the correlation of the first signal and the second signal in a forward mode and a backward mode along a transverse direction.
