<p>PROBLEM TO BE SOLVED: To provide a digital beam formation type(DBF type) radar device where a device scale is reduced by commonly utilizing the transmission system of a phased array antenna(PAA) configuration also at the time of receiving signals. SOLUTION: A reception beam that is subjected to DBF processing is formed from a reception signal from all element antennas 5a-5h, at the same time a reception signal from the element antennas 5c-5f used for transmission is synthesized by commonly using an azimuth signal distributor 2 for distributing a transmission signal for forming a reception beam that is subjected to PA processing, thus reducing the processing region of the reception signal that is subjected to the DBF processing.</p> |
