Abstract
An array antenna device includes a plurality of antenna elements arranged to include a first antenna element arrangement in which antenna elements are arranged at element intervals having predetermined periodicity and a second antenna element arrangement in which antenna elements are arranged at element intervals having predetermined periodicity different from the periodicity in the first antenna element arrangement. The array antenna device includes a control unit configured to remove erroneous detection caused by a grating lobe based on a comparison of a detection result by an array antenna of the first antenna element arrangement and a detection result by an array antenna of the second antenna element arrangement.
