Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples of implementation. It should be understood that the specific implementation cases described here are only used to explain the present invention, not to limit the present invention.

[0022] Such as figure 1 As shown, the radar antenna element of the present invention is in the transportation state, the load-bearing rods 1 are arranged on the support arm 8 closely to each other, and the arrays are distributed in parallel along the load-bearing rod 1, as figure 1 Shown in (a); During the working state, the bearing rod 1 is first deployed along the support arm 8, as figure 1 As shown in (b); then part of the antenna element is rotated 90 degrees, so that the element is in a cross state, as shown figure 1 (c) shown.

Abstract

The invention relates to a radar antenna array rotating mechanism, the radar array is arranged on a plurality of load-bearing rods, characterized in that: include rotating mean, connecting rod, end tie rod, push-pull fixture, each antenna array is mounted on a rotating device, Two adjacent rotating devices of the same load-bearing lever are connected in series through connecting tie rods for transmitting motion and locking force between the rotating devices, and the rotating device at the end is connected with the push-pull jig through the end tie rods, and each rotating device is driven to rotate by pushing or pulling the push-pull jig. The radar antenna array rotating mechanism has the advantages of simple device, small overall occupied space, easy processing and maintenance, and high locking reliability.

Description

technical field [0001] The invention relates to the field of ground mobile radar antennas, in particular to an array element rotation mechanism for planar radars. Background technique [0002] With the needs of information warfare and the development of radar detection technology, ground vehicle radar has two major development trends, the increase in the size of the antenna array and the rapidity of erection. On the one hand, for a larger detection distance, it is necessary to increase the area of ​​the antenna front. Due to the limitation of the transportation conditions of the vehicle radar, the antenna front must have a certain folding ability; on the other hand, the faster erection speed requires The shorter the folding time of the antenna array. At present, in the field of ground vehicle radar, various antenna folding mechanisms gradually replace manual installation to increase the speed of radar erection. [0003] The radar element is the core component of the radar,...
