Zusammenfassung:	PROBLEM TO BE SOLVED: To detect the rotational angle of an antenna from an angular signal of one channel. SOLUTION: Because a rotary part reciprocated and rotated in a prescribed angular range is rotated with a first velocity pattern in a first rotational direction and rotated with a second velocity pattern in a second rotational direction, so that a signal processor in which a pulse signal for every unit angle is input as an angular signal can reverse the rotational direction corresponding to the signal pattern of the angular signal of one channel, and can detect the reversal of the rotational direction from the switching of the signal pattern. Thus, the rotation angle of the rotary part in the angular range can be detected from the determined rotational direction and the number of pulses of the angular signal after the reversal.
