1. A vehicle-mounted radar system comprising:
a plurality of laser radars that irradiate a surrounding of a vehicle with a laser beam and receive light reflected by an object around the vehicle; 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,
wherein the control device
determines whether or not the laser beam of any of the plurality of laser radars is blocked by the object, and thus an undetected area is created, based on a recognition result of the object, and
when the laser beam of one of the plurality of laser radars is blocked by the object, and thus the undetected area is created, expands a detection range of another laser radar adjacent to the one laser radar so that at least a portion of the undetected area is allowed to be detected.
