Abstract
A radar device according to one aspect of the present disclosure includes a plurality of transmitting antennas, a plurality of receiving antennas, a first azimuth estimation unit, a second azimuth estimation unit, and a selection unit. The first azimuth estimation unit estimates a first azimuth by coherently processing first received signals received by a virtual array. The second azimuth estimation unit estimates a second azimuth by, between transmissions or receptions, coherently processing second received signals received by an antenna array. The selection unit adopts the first azimuth or the second azimuth depending on the ambient environment and/or the detected situation of the target.
