A radar device according to the embodiments includes a deriving unit and a determining unit. The deriving unit derives, based on a received signal acquired by receiving a reflected wave obtained by reflecting a radar transmission wave transmitted to a periphery of an own vehicle on a target located on the periphery, a parameter related to the target and a detection distance of the target. The determining unit determines, from a given characteristic of the parameter and the parameter and the detection distance derived by the deriving unit, whether the target existing in a traveling direction of the own vehicle is a target that collides with the own vehicle when the own vehicle advances in the traveling direction or a target that does not collide with the own vehicle when the own vehicle advances in the traveling direction.
