Patent ID: 8633849

Claim:
A radar device which is mounted on a vehicle and is operable to scan a transmission wave to detect a detection point representing a position of an object disposed around the vehicle on the basis of a reflected wave of the transmission wave from the object, the radar device comprising: a memory; and a signal processor configured to: read information of detection points from the memory which stores the information of the detection points including a first representative detection point closest to the vehicle, which are detected in a first scanning; determine whether or not the detection points of the read information are continuously detected in a second scanning after the first scanning; set a detection point which is second-closest to the vehicle and which is continuously detected in the second scanning from among detection points disposed within a predetermined range from the first representative detection point in the first scanning as a second representative detection point in the second scanning when the first representative detection point is not detected in the second scanning; and determine that the first representative detection point and the second representative detection point are information of different objects when the second representative detection point exists at a position distant from a position of the first representative detection point by a distance equal to or more than a predetermined distance.
