<p><P>PROBLEM TO BE SOLVED: To accurately detect a turn angle even when an antenna reverses at a position deviated from an expected reversing position in a radar device of a mechanical scanning method. <P>SOLUTION: This signal processor for receiving an angle signal when a turning section reciprocating and turning within a predetermined angle range turns by unit angle comprises a reverse detecting means for detecting the reverse of the turn direction of the turning section based on state transition of the angle signal, and a turn angle detecting means for detecting the turn angle of the turning section based on the angle signal input after detection of the reverse. Based on the angle signal input after a first reverse of the turning section is detected by the reverse detecting means and until a second reverse is detected, the turn angle detecting means corrects the turn angle based on the angle signal input after the second reverse is detected, so that it can detect the turn angle based on the angle signal from the expected reversing position. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
