摘要： A driving lane detection device of the present disclosure includes: an object detector, a vehicle detector, and a driving lane detector. The object detector generates object data relating to a distance and direction from the vehicle to an object and a movement direction of the object based on one or more reflection waves that are a radar signal transmitted by a radar device and reflected by the one or more object. The vehicle detector detects each object as at least one of a parallel-running vehicle running in a same direction as the vehicle or an oncoming vehicle running in an opposite direction to the vehicle, based on the object data. The driving lane detector detects a driving lane based on the distance and direction from the vehicle to at least one of the detected parallel-running and the detected oncoming vehicles and lane information on at least one of lane widths and a number of lanes of a road on which the vehicle is running.

摘要： Provided is a radar apparatus including: an estimation circuit; and a processing circuit. The estimation circuit outputs a plurality of pieces of data each including information in which a distance to a target and a direction to the target are estimated based on a reception signal including a reflected wave that is a radar signal reflected by the target. The processing circuit determines a range side lobe component in the target based on the estimated distance and the estimated direction of one or more pieces of data selected from the plurality of pieces of data.
