The present invention relates to a method for classifying objects detected by a vehicle mounted radar located in front of said vehicle for transmitting a radar microwave signal and for receiving reflexes thereof from objects positioned in front of said vehicle, said melted comprising the steps of: tracking a radar reflex from an object located in front of said vehicle as the calculated distance from said vehicle to said object, as derived based upon the time of flight of said radar reflex, decreases; monitoring changes in the amplitude of said radar reflex from said object is said calculated distance from said vehicle to said object decreases; and classifying said object as an overhead object or a ground level object based upon the said changes in the radar reflex amplitude.
