Description

Technical field [0001] The present invention relates to the field of radome technology, in particular to a variable thickness of a dual-frequency millimeter wave high transmittance bulletproof radome. Background [0002] Precision guidance is an important requirement for weapon strikes, and the radome, as a key component to protect the antenna system from external environmental influences, has good electromagnetic penetration characteristics in electrical performance and can resist external harsh environments such as rain, snow, hail, sand and dust and solar radiation erosion in mechanical performance. However, with the improvement of military demand, conventional radomes can not meet the needs of the battlefield, and millimeter-wave radar has a high resolution, and has a certain degree of anti-interference, anti-stealth capabilities, so that the development of multi-frequency millimeter-wave radomes has become one of the current research hotspots, and in order to improve the sur...

Problems solved by technology

However, with the improvement of military requirements, the conventional radome cannot meet the needs of the battlefield, and the millimeter-wave radar has high resolution, and has certain anti-jamming and anti-stealth capabilities, making the development of multi-frequency millimeter-wave radome has become a One of the current research hotspots, and in order to improve the survivability of the radome on the battlefield, the radome should also have excellent bulletproof performance

[0003] However, when the antenna is at different scanning angles, the incident angles of electromagnetic waves at different positions of the radome are different, and different incident angles correspond to different Electromagnetic transmittance, which leads to a large difference in the electromagnetic transmittance of the radome structure with uniform wall thickness when the antenna is at different scanning angles, which will seriously affect the precision of weapon guidance, thereby reducing the precision strike capability of weapons
