RADAR APPARATUS FOR VEHICLE

A radar apparatus for use on a vehicle has a radar beam scanning mechanism for scanning a scan area with a radar beam substantially in parallel to a road surface on which the vehicle is running, and an object detector for receiving reflected waves of the radar beam to create a detected object image, based on the reflected waves. The object detector is provided with a ghost determination device for determining whether a detected object image created is a ghost. Therefore, the radar apparatus can eliminate a detected object image determined as a ghost out of detected object images created.
