Abstract

PURPOSE:To reduce a mounting space with a simple construction, by a method wherein light passing through a through hole from a light emitting element is outputted from a light receiving element and the resulting output signal is received to determine an angle of rotation, rotational speed and the like of a radar antenna with a rotation calculator. CONSTITUTION:A motor 1 is rotated to transmit a driving force to a radar antenna 5 through gears 3 and 4. An emission control signal from an emission controller 17 is applied to a light emitting element 11, light from the element 11 is sent to a light receiving element 12 passing through a through hole and receiving this light, the element 12 is made conductive to output a high-level detection signal P during the reception of light. The signal P is shaped in the waveform with a waveform shaping circuit 13 to be sent to a rotation calculator 14. The signal P is sent to a radar display 15 through the rotation calculator 14. Thus, a display device 15 calculates an angle of rotation from high-level counts of the signal P to be shown on a display screen.
