1. A method of detecting a velocity of a target for a vehicle, the method comprising:
detecting the target using a detection sensor;
calculating, by a tracking filter in a first calculation operation, a first longitudinal velocity at a detection point of the target detected by the detection sensor;
computing, in a computation operation, longitudinal computation velocities at a plurality of detection points when the plurality of detection points is detected;
grouping, in a grouping operation, the longitudinal computation velocities;
calculating, in a second calculation operation, a second longitudinal velocity of the target based on the longitudinal computation velocities of a group of the grouping including a largest number of detection points;
calculating, in a final calculation operation, a final longitudinal velocity of the target by using the first and second longitudinal velocities; and
controlling the vehicle based on the calculated final longitudinal velocity of the target.
