Abstract

The invention discloses a large vehicle-mounted parabolic antenna capable of being folded and unfolded repeatedly, and particularly relates to the field of parabolic antennas. Comprising a vehicle-mounted base, a yawing base, a pitching support, a parabolic antenna outsole, an antenna lobe and an antenna back frame, the vehicle-mounted base is arranged on a special vehicle, the yawing base is arranged on the vehicle-mounted base, the pitching support is rotatably connected to the yawing base, the parabolic antenna outsole is fixedly connected to the pitching support, and the antenna lobe is fixedly connected to the pitching support. An antenna feed source and an annular driving assembly located below the antenna feed source are installed on the parabolic antenna outsole, an embedding groove is formed in the parabolic antenna outsole, hooke hinges are rotationally connected into the embedding groove, antenna lobes are connected to the hooke hinges, the antenna lobes are provided with hydraulic rods, and the hydraulic rods are connected between the annular driving assembly and the antenna lobes. By adopting the technical scheme of the invention, the problem that the parabolic antenna and the back frame cannot be quickly and flexibly assembled and disassembled is solved, and the rotary folding and unfolding efficiency of the antenna lobes can be improved.

Description

technical field

[0001] The invention relates to the field of parabolic antennas, in particular to a large vehicle-mounted parabolic antenna that can be retracted repeatedly. Background technique

[0002] As the world's military powers accelerate the development of the "full-dimensional intelligent perception system" battlefield mode, the construction of reconnaissance, surveillance and early warning systems and battlefield information transmission systems play an increasingly prominent role in modern warfare. The establishment of a full-dimensional intelligent perception system is inseparable from various military radars. Military radars have the characteristics of all-weather, all-weather, and high data rates in large airspace. The most basic functions are radio detection and positioning, which can be obtained in different levels of combat systems. The real-time information of the target, the real-time position, the accurate distance of the target, the possibility of existe...
