Abstract: In a radar device mounted in a host vehicle, a radar transmitting unit transmits a radar signal; a light detection unit detects ON or OFF of a light of another vehicle in which the radar device is mounted; and a timing control unit sets a transmission timing of the radar signal and a light ON timing of a light of the host vehicle, the light ON timing is synchronized with the transmission timing on basis of detected ON or OFF of the light of the other vehicle. The set transmission timing is different from a transmission timing of a radar signal of the radar device mounted in the other vehicle.

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.

Abstract: A road information detector acquires road information by emitting a beam via a variable directivity transmission antenna to a road sign having plural flat portions and includes a transceiver that controls the antenna to scan the beam by switching an emission angle including an azimuth angle relative to the front direction of a vehicle and receives, as reflected wave signals, waves reflected by the flat portions, a distance and reflected wave intensity detector that detects a distance between the vehicle and each of the flat portions and a reflected wave intensity of each of the reflected waves, an emission angle detector that detects the emission angle based on the reflected wave signal, and a road information analyzer that acquires the road information by generating a heat map based on the emission angles, distances, and reflected wave intensities and analyzing the heat map using a threshold value of the wave intensity.
