Abstract

The invention discloses a high-wave-transparent light honeycomb sandwich bulletproof radome which comprises a radome main body. A concave cover body is in the radome main body, an inner core of the radome main body is a honeycomb layer for supporting, and an ultrahigh molecular weight polyethylene fiber layer for ballistic protection with a matched shape is outside the honeycomb layer. The radomemain body is cylindrical and comprises a side surface portion as a side surface and a bottom surface portion as a bottom surface, the side surface portion has an arc shape which is contracted at two ends of a middle ridge, the bottom surface portion is planar, the bottom surface portion and the side surface portion are connected by arc bending unit, the angle between the bottom surface portion andthe side surface portion is larger than or equal to 90 degrees and smaller than 120 degrees, and the bulletproof radome is made of ultrahigh molecular weight polyethylene as a raw material and has high wave transmission performance and bulletproof performance.

Description

technical field [0001] The invention belongs to the field of antenna devices, and in particular relates to a bulletproof radome with high wave-permeability and lightweight honeycomb sandwich. 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, improved ballistic performance and light weight of radomes is becoming more and more urgent. [0003] At present, the mat...
