Abstract: One of a transmitting array antenna and a receiving array antenna includes a first antenna group and a second antenna group. The first antenna group includes one or more first antenna elements of which the phase centers of the antenna elements are laid out at each first layout spacing following a first axis direction, and a shared antenna element. The second antenna group includes a plurality of second antenna elements and the one shared antenna element, and the phase centers of the antenna elements are laid out in two columns at each second layout spacing following a second axis direction that is different from the first axis direction. The phase centers of the antenna elements included in each of the two columns differ from each other regarding position in the second axis direction.

Abstract: A vehicle-mounted radar device has: a radar transmitting circuit transmitting a radar transmission waves to be reflected at a target; a radar receiving circuit receiving the reflected waves; a radar's axial deviation detecting circuit deciding whether the radar axis of the radar device has a deviation, according to the difference between a first value (distance between the vehicle and the known still object based on a shape of the known still object) and a second value (distance between them at a time when a radar reflected wave having attenuated power of the known still object among the radar reflected waves is received); and an axial deviation notifying circuit making a notification of the axial deviation.
