Zusammenfassung:	PROBLEM TO BE SOLVED: To correct a deviation of a feeding phase of an antenna element, in a rader device using a series feeding type array antenna as a transmission/reception antenna.SOLUTION: A feeding line 100 of a transmission array antenna 10 is connected to a correction line 102 at a terminal. A switch 103 is provided between a first antenna element 101a counted from a power reception point side of a reception array antenna 11-1 adjacent to the transmission array antenna 10, and the power reception point. During correcting action, the correction line 102 and the power reception point of the reception array antenna 11-1 are connected, and the power reception point of the reception array antenna 11-1 and the antenna element 101a are disconnected, by the switch 103. A deviation of phase change amount can be detected from a signal received through the correction line 102 during the correcting action, and a deviation of a feeding phase of the antenna element 101 can be corrected.
