Abstract
There is disclosed a radar device including: an information storage to store position information of a mobile entity existing independently of the radar device; and a transmission array antenna having a transmission sub-array antenna which transmit a signal to the mobile entity. The radar device estimates a parameter such as arrangement relation and a transmission phase of the sub-array antenna by using amplitude phase information in a plurality of reception sub-array antennas that have received reflected signals from the mobile entity with respect to the reception signals, and position information of the mobile entity that is stored in an information storage, and performs operation of radar using the estimated parameter. With this configuration, there can be obtained a radar device that is able to estimate a parameter such as arrangement relation and a transmission phase of a sub-array antenna without installing a transmission source of reference radio waves.
