Description
Technical field
The utility model belongs to radar protection field, is specifically related to a kind of radome for shipborne radar.
Background technology
Because shipborne radar is in high damp and hot marine environment, so the antenna of radar must have the protection of radome.The marine environment of high heat, high humidity, high salt fog requires that radome must seal reliably.At present, the sealing of radome adopts the process of rubber seal more, and its shortcoming is: (1), under the salt fog and high ultraviolet irradiation environment of marine environment, accelerated ageing understood by fluid sealant, and finally causes seal failure, have impact on the useful life of radome; (2) sealant sealing also can affect presentation quality.
Utility model content
For solving the defect that existing radome technology exists, the utility model devises a kind of radome for shipborne radar.
For a radome for shipborne radar, comprise flange 1, outer cover 2; Described flange 1 is in circular, and axially a side is uniformly distributed along the circumference and is provided with projection 11, described uniform projection 11 forms zigzag; Described outer cover 2 is in bowl-shape, and its opening perimeter is laid with groove, and the projection 11 that each groove is corresponding with flange 1 is connected, and forms bayonet socket one to one and connects, make flange 1 and outer cover 2 split be connected to form an entirety.
The material of described flange 1 is metal, and the material of outer cover 2 is aramid paper honeycomb.
The inside and outside surface of described flange 1 and outer cover 2 is all affixed with skinning layer.
The material of described skinning layer is fiberglass, and the thickness of skinning layer is 1mm.
The thickness of described outer cover 2 is equal with the thickness of projection 11.
The projection 11 of described flange 1 all scribbles foamed glue with the junction of outer cover 2 groove.
Advantageous Effects of the present utility model:
(1) hood of the present utility model adopts aramid paper cellular material, ensure that the wave transparent safeguard function of radome; Bottom adopts metal flange sealing, and metal flange is not yielding in forming process, is beneficial to post-production school shape, and ensure that the evenness of sealing, enhance rigidity;
(2) the utility model adopts the Sawtooth connection of hood and flange to seal, and adds the bond area between flange and hood, enhances adhesive strength, thus improve the impact resistance of radome;
(3) the inside and outside surface of the utility model flange and hood is all affixed with skinning layer, radome is not easily corroded under high salt fog marine environment, extends the useful life of radome
.
