Problems solved by technology

However, separate transportation will cause the following problems: (1), inevitably increase the installation / disassembly time, greatly prolonging the deployment time of the entire radar system; high demands
[0004] The existing antenna framework deployment schemes are mostly manually installed and disassembled. Multiple load-bearing rods are installed and locked separately. Although this method has high reliability, it is time-consuming and laborious to install, and the deployment time is very long. Can no longer meet the needs of modern warfare

Abstract

The invention relates to the technical field of military vehicle-borne radar, and more particularly relates to a foldable radar antenna framework and a working method thereof. The foldable radar antenna framework comprises a main supporting frame, supporting arms, guide rails, antenna bearing rods, traction mechanisms, driving mechanisms and locking mechanisms. The supporting arms are arranged on the main supporting frame. The guide rails are fixedly connected on the supporting arms. The antenna bearing rods are arranged above the supporting arms. The traction mechanisms are arranged on the two adjacent antenna bearing rods. The driving mechanisms are arranged between the guide rails and the antenna bearing rods. The locking mechanisms are arranged between the support arms and the antenna bearing rods. The antenna framework is convenient to install and disassemble, the traction mechanisms have high reliability, and a linkage locking mode is adopted so that installing / disassembling time of the antenna framework can be substantially reduced, and the maneuverability index of overall radar deployment can be enhanced.

Description

technical field [0001] The invention relates to the technical field of military vehicle-mounted radar, and more specifically relates to a retractable radar antenna framework and a working method thereof. Background technique [0002] High mobility is one of the key technical indicators of ground vehicle radars. In recent years, high mobility radars are mainly based on radars with small-caliber antennas. With the needs of information warfare and the development of radar detection technology, in order to detect incoming targets in advance and improve the detection distance, large-scale planar array antennas have been widely used in ground medium and long-range three-coordinate military radars. Due to the limitations of carrying capacity and transportation conditions, large planar antennas must be processed in blocks to meet cross-country transportation requirements. Therefore, in the process of radar erection, it is necessary to carry out links such as antenna assembly and sp...
