ABSTRACT:
A vehicle radar includes a vehicle in front from being a target when the vehicle shifts to another lane by decreasing certainty of the vehicle as the target. The vehicle radar calculates a relative distance and a relative speed between each of target objects and a vehicle on which the vehicle radar is provided by transmitting forwardly a frequency modulated carrier wave and receiving the carrier wave reflected by each of the target objects. A certainty level represented by probability of existence of the target objects is calculated based on a relationship between a currently detected condition of the target objects and a previously detected condition of the target objects. The certainty level of the target objects is changed when it is determined that the target objects move away from a lane in which the vehicle is moving so that the target objects are excluded from targets to track.
