A Modular Large Array Radar Antenna Mechanism

Abstract

The invention relates to a modular large-array surface radar antenna mechanism. The modular large-array surface radar antenna mechanism comprises a first longitudinal rod and two second longitudinal rods, wherein a lead screw driving mechanism is arranged on the first longitudinal rod, the two second longitudinal rods are symmetrically arranged at two sides of the first longitudinal rod and are connected with the lead screw driving mechanism via a first connection rod, the first longitudinal rod is connected with the first connection rod via a second connection rod, and a plurality of oscillators are arranged on both of the first longitudinal rod and the two second longitudinal rods. In the antenna mechanism, by combination of the lead screw driving mechanism, the first connection rod andthe second connection rod, folding and unfolding of the antenna mechanism can be achieved, the antenna mechanism has the characteristics of large unfolding size and small folding size, the large powerrequirement of radar when the antenna mechanism is unfolded can be met, the requirement on high maneuverability and transportation performance of the radar when the antenna mechanism is folded is met, meanwhile, an antenna array surface with a relatively large size can be formed by combining a plurality of antenna mechanisms.

Description

technical field [0001] The invention relates to the technical field of antenna mechanisms, in particular to a modular large-array radar antenna mechanism. Background technique [0002] In order to improve the detection power of the radar, the most direct measure is to increase the size of the antenna array; in order to improve the maneuverability of the radar and thus improve the survivability on the battlefield, the radar layout is required to be compact and single-vehicle integration should be achieved as much as possible; in order to facilitate the radar For transportation, the smaller the size of the radar, the better. Try to carry out road and rail transportation without any disassembly. [0003] In order to achieve the above contradictory goals at the same time, the current radar usually adopts the method of simply splitting the antenna array, that is, splitting the antenna array into 2 or 3 sub-arrays, and the sub-arrays are connected by hinges. Folds to reduce overa...

Problems solved by technology

This splitting method is only applicable to the case where the size of the array is not very large. When the size of the array is large, the sub-arrays obtained by splitting still have a large size, which has great restrictions on the radar layout, and it is difficult to integrate single vehicles. However, the purpose of improving the mobility and transportability of the radar cannot be achieved; in addition, the split sub-arrays are quite different, the structure is complex and not universal, and it does not conform to the serialization and generalization of today's equipment design idea
