A method and apparatus are provided for estimating the velocity vector of a
remotely sensed object or group of objects using either ultrasound or
electromagnetic radiation. The movement of the object is determined by
emitting and receiving a pulsed field with spatial oscillations in both
the axial and transverse directions. Using a number of pulsed emissions
and the transverse spatial oscillations the received signal is influenced
by transverse motion and a new autocorrelation estimator is used for
determining the velocity vector.
