Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, in t...

Abstract

The invention discloses a wave-transparent radome, which comprises a radome prefabricated body. The inner surface and the outer surface of the radome prefabricated body are connected with a pluralityof layers of first fiber cloth; the radome prefabricated body is formed by splicing a plurality of foam prefabricated bodies in polygonal curved surface structures; and the adjacent prefabricated bodies in the radome prefabricated body and the prefabricated bodies and the first fiber cloth are subjected to vacuum bonding through resin and are cured into a whole. The preparation of the foam prefabricated body ensures the conformability of the radome sandwich foam in complex curvature surface; all layers of radome bodies are cured layer by layer in the curing process, so that the interlayer defects of the radome bodies are reduced; the state of each layer of the radome body can be inspected layer by layer, so that the overall quality of the radome is ensured; due to the design of the multiple layers of sandwich foam, the radome has excellent wave-transparent performance under wide-band and high-frequency working frequencies, and the electrical performance of the radome is improved; and the sandwich foam radome body structure sewed between the layers effectively increases the overall strength and rigidity of the radome, and the bearing capacity of the radome is improved.

Description

technical field [0001] The invention relates to the technical field of radar radome, in particular to a wave-transparent radome. Background technique [0002] The radome, also known as the radome, is a shell structure that protects the antenna from the natural environment. As an important part of the radar system, its importance lies in providing an all-weather working environment for the radar antenna. Now it is widely used in large ground Radome, Airborne Radome, Shipborne Radome, Missile Radome, etc. As the electromagnetic window to protect the antenna, the radome must not only meet the wave-transmission requirements of the antenna, but also maintain a stable and complete state under the action of the load, without harmful deformation and damage, and the structural strength meets safety. [0003] According to the cross-section of the cover wall, the radome can be divided into uniform single layer, A interlayer, B interlayer, C interlayer and multi-layer structure. At pr...
