Abstract

The invention relates to a large phased array radar antenna frame structure and a manufacturing method thereof. The large phased array radar antenna frame structure is formed by riveting a casting frame, multiple I-shaped aluminum beams, connecting angle members, a left longitudinal beam, a right longitudinal beam, an upper cross beam, a lower cross beam, four-corner joints, waveguide supporting strips, a skin, a supporting plate and the like. 128 slotted waveguides about 3 meters in length and other radar subsystems are mounted on a frame. By the frame, a bottleneck of difficulty in guaranteeing accuracy of a large phased array radar antenna is broken through, rigidity is improved by about 20-30% under the circumstance of same weight, the frame is low in cost and attractive in appearance, and environmental adaptability of the whole antenna is greatly improved after high-temperature pressure-sensitive adhesive tapes are pasted on the surfaces of the slotted waveguides. Designing and manufacturing technology of the large phased array radar antenna is already successfully applied in certain key military radar, is about to be applied in certain foreign-trade radar, is expected to bring about bigger economic benefit, military benefit and social benefit in the future and has wider application prospect.

Description

Technical field [0001] The invention belongs to the field of radar engineering, and relates to a phased array radar antenna frame structure and a manufacturing method with large volume, large weight, high rigidity requirement and high integration. Background technique [0002] The phased array radar antenna frame is not only the installation foundation of the antenna, but also the installation foundation of other radar subsystems. It is characterized by large volume, heavy weight, high heat consumption, high rigidity requirements, and high system integration. As an important basic structure of radar, the design of antenna frame structure is one of the important contents of the whole radar system structure design. The quality of its design directly affects the quality of the radar. The design of large antenna frame structure has increasingly become an influence on phased array radar. An important part of technical and tactical indicators. [0003] The existing welded or riveted fr...
