Abstract
A vehicle, system and method of estimating a velocity of an object with respect to the vehicle is disclosed. The system includes a plurality of radars associated with the vehicle and a processor. The plurality of radars provide a coarse estimate of the velocity. The processor obtains a plurality of velocity hypotheses based on the coarse estimate of the velocity of the object, determines a likelihood for each of the plurality of velocity hypotheses, and chooses a velocity hypothesis having as the estimate of velocity based on the determined likelihood.
