Abstract

The invention discloses a flip antenna synchronous stretching system and a control method. The system includes a central framework, horizontal stretching mechanisms, an antenna column framework and ahydraulic system, wherein the central framework is hinged with the horizontal stretching mechanism, the horizontal stretching mechanisms can perform flipping motion around a hinge point, the antenna column framework is disposed on the horizontal stretching mechanisms, and the hydraulic system controls the horizontal stretching mechanisms for realizing flipping and horizontal stretching operation of the horizontal stretching mechanisms. The system is advantaged in that a side block antenna consists of two sets of horizontal stretching mechanisms, the side block column framework load is evenly distributed on each arm of the two sets of horizontal stretching mechanisms, stiffness of the entire antenna front is improved, and erection requirements of large-diameter antenna fronts are met.

Description

technical field [0001] The invention relates to the technical field of radar antennas, in particular to a flip-up antenna synchronous deployment system and a control method. Background technique [0002] In recent years, the air defense system with ground radar as the core is facing serious threats such as electronic interference, stealth aircraft, and anti-radiation missiles. In order to improve its own survivability, ground radar has the ability to quickly and reliably automatically erect / withdraw the antenna array It is one of its basic requirements. In addition to meeting the rapid maneuvering needs of the battlefield, it also needs to meet the requirements of sea, land and air loading and transportation specifications. [0003] The vehicle-mounted active phased array antenna array is usually folded, turned over and other actions to complete the erection and withdrawal. The advantages of foldable antennas are small size, simple operation, and high reliability. However, ...
