Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 2:
3. A vehicle-mounted radar system comprising:
a plurality of laser radars that receive light reflected by an object around a vehicle while scanning a surrounding of the vehicle by changing an irradiation direction of a laser beam; and
a control device that controls the plurality of laser radars and recognizes the object based on light reception results of the plurality of laser radars, the system further comprising
an own-vehicle speed detector that detects a speed of the vehicle,
wherein the control device
when the speed of the vehicle detected by the own-vehicle speed detector is less than a predetermined speed set in advance, controls the plurality of laser radars in a first scanning pattern in which scanning timings of the plurality of laser radars are the same, and
when the speed of the vehicle detected by the own-vehicle speed detector is equal to or more than the predetermined speed, controls the plurality of laser radars in a second scanning pattern in which the scanning timings of the plurality of laser radars are different from each other, and an irradiation direction of one of adjacent laser radars is the same as an irradiation direction of another laser radar with a delay of half a cycle of an entire scanning by the plurality of laser radars.
