Research on efficient deployment and retraction system of large high mobility radar antenna array

Abstract In order to solve the problems of low efficiency and low reliability of large array radar, an array expansion and retraction system is designed. The system uses electromechanical hydraulic integration design technology to realize the rapid expansion and retraction of the antenna and complete the conversion of working state and driving state. The antenna array with a width of 13.5 meters can be folded to a width of 2.5 meters, and the extension ratio is greater than 5. The synchronous rod is used to realize the synchronous unfolding and retracting action of the array deployment mechanism. The deployment and retraction system has strong adaptability to the environment and is high reliability. The erection time of the super large antenna array is controlled within 1 minute, which greatly improves the erection efficiency of the large antenna array and provides a reference for the system design of this kind of mechanism.
