Abstract

The invention relates to a double-pass band wave-transparent structure with a wave-absorbing function, comprising a skin layer, a foam layer, a loss layer and an FSS layer, and from top to bottom are the skin layer, the loss layer, the skin layer, the foam layer, and the skin layer 1. The frequency selective surface layer and the skin layer are bonded together between the layers. The present invention has the dual functions of simultaneously realizing Ku and Ka two-band wave transmission and low-frequency wave absorption, and can reduce the backward electromagnetic force outside its working frequency band. Advantages of scattering.

Description

technical field [0001] The invention relates to the technical field of radar wave transmission, in particular to a double passband wave transmission structure with wave absorption function. Background technique [0002] In all kinds of weapons and equipment installed with radar sensors, the low detectability of the radar system is improved by the radome composed of a special radar wave-transmitting structure. The traditional radar wave-transmitting structure does not have low detectability, and although the traditional radar wave-absorbing structure has a significant effect on improving the low detectability of the radar, the traditional radar wave-absorbing structure is not suitable for radomes. [0003] The traditional radar absorbing structure is mainly composed of an impedance layer and a metal substrate separated by a dielectric layer. At present, there is mainly a Salisbury screen composed of a single-layer impedance layer, which can only achieve wave-absorbing charact...
