Abstract
A radar system includes a detection-control circuit for transmitting and receiving the beam of a millimeter-wave signal for detecting a relative position and a relative speed to a target, and a scanning unit for scanning the direction of the beam over a predetermined range. The state of the scanning unit can be switched between a resting state wherein scanning is stopped and the beam is directed towards the center of the scanning range while the detection-control circuit continues detection control, and a scanning state wherein the direction of the beam is scanned over a predetermined range.
