Abstract:
1. A vehicle-mounted radar apparatus for transmitting radar waves outward from a vehicle on which the vehicle-mounted radar apparatus is mounted, the vehicle being hereinafter referred to as a radar-mounting vehicle, and receiving the radar waves reflected from an object to acquire information about the object, the vehicle-mounted radar apparatus comprising: a target detection unit that transmits and receives the radar waves to detect positions of targets that are reflection points of an object reflecting the radar waves; a representative target selection unit that selects one of the targets detected by the target detection unit that fulfills a predetermined representative-target designation condition for designating a representative of the targets detected by the target detection unit; a same-object target selection unit that selects, from the targets detected by the target detection unit, targets that fulfill a predetermined same-object target selection condition for determining which of the targets detected by the target detection unit belongs to the same object as the representative target, the representative target and the targets selected by the same-object target selection unit other than the representative target forming together a same-object target group, and the object that each target of the same-object target group belongs to being referred to as a specific reflecting object; an object position determination unit that sets a target inclusion region so that all the targets of the same-object target group are included in the target inclusion region, thereby determining a position of the specific reflecting object; and a large-vehicle determination unit that determines whether or not the specific reflecting object is a large vehicle, a width of which is greater than 1.8 m, on the basis of at least one of a number of targets of the same-object target group and a power spectrum indicative of reflection wave received powers for the respective targets of the same-object target group.
