Problems solved by technology

[0004] At present, bulletproof radome is often used below the Ku frequency band, and can only be used in a single frequency band
In addition, the commonly used material for the finished bulletproof radome is aramid fiber, while ultra-high molecular weight polyethylene is still in the experimental stage, and there is no finished product report

Embodiment Construction

[0019] Below, combine figure 1 The present invention will be further described with specific examples.

[0020] A Ku / Ka dual-band high-transmission bulletproof radome, the bulletproof radome is formed by pressing ultra-high molecular weight polyethylene with a single-layer structure, and the thickness of the wave-transparent surface of the bulletproof radome is 6-8mm.

[0021] The manufacturing method of the above Ku / Ka dual-band high-transparency bulletproof radome comprises the steps of: placing ultra-high molecular weight polyethylene in the mold of the bulletproof radome; setting the temperature during pressing to be lower than the melting point temperature of ultra-high molecular weight polyethylene by 20°C From ℃ to 30℃, the pressure is controlled at 0.5-16.5Mpa, and the heat preservation time is set; the pressure is maintained during the cooling process, and the pressure can only be released when it is lower than 60℃.

[0022] In the embodiment, the temperature during ...

Abstract

The invention provides a Ku / Ka dual-band high-transparency bulletproof radome and a manufacturing method thereof. The bulletproof radome is formed by pressing a single layer of ultra-high molecular weight polyethylene, and is suitable for integral manufacturing of the bulletproof radome. The invention realizes the dual-band high wave-transmitting performance of the radome, and has better bulletproof performance.

Description

technical field [0001] The invention relates to the technical field of manufacturing a dual-band high-transmission bulletproof radome, in particular to a Ku / Ka dual-band high-transmission bulletproof radome and a manufacturing method thereof, which is suitable for the overall manufacture of a bulletproof radome. Background technique [0002] The radome is also called the radome. Its function is to protect the antenna and the antenna system from the damage of the external harsh environment such as sandstorm, rain and snow, hail, salt spray, dust, insects and low temperature and high temperature weather, and at the same time provide the antenna system with a class of transparency. Electromagnetic windows are usually physically isolated environments made of natural or synthetic composite materials. With the gradual increase of the threat level of conventional weapons, conventional radomes can no longer meet the needs of the battlefield. The demand for high-frequency operation, ...
