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.
Claims17
A radar system comprising:
- a detection-control circuit for transmitting and receiving a detection signal and for detecting at least one of a relative position and a relative speed to a target;
- a scanning unit for scanning the direction of a beam of the detection signal over a predetermined range;
- and
- a beam-scanning control unit;
- wherein
- the beam-scanning control unit switches the state of the scanning unit between a resting state wherein the direction of the beam is fixed to a predetermined position while the detection-control circuit continues detection controlling, and a scanning state wherein the direction of the beam is scanned over a predetermined range.
