ンテナの回転制御装置。[Claims for Utility Model Registration] A radar antenna that is rotated in high-speed sequential order by a single-phase synchronous motor, has a detected object installed at a suitable position on its rotation axis, and one of the pulses generated when the detected object rotates and passes. first and second pulse generating means that sequentially generate pulses such that the pulses overlap (time t0 or more); and a third pulse generator that generates a pulse signal having a width t0 from the time point at which the first pulse is generated. means, first determining means for determining the order of generation of the first and second pulses, and second determining means for determining the level state of the second pulse at the trailing edge timing of the third pulse. and a signal generating means that outputs a signal from the outputs of the first and second determining means only in a high-speed reverse rotation state, and a switch that stops power supply to the motor for a certain period of time in response to the generated signal. Radar antenna rotation control device.
