Abstract

The embodiment of the invention provides a low-scattering airborne aperture structure. The low-scattering airborne aperture structure comprises a metamaterial antenna housing, a conformal antenna, a multipath reflection wave-absorbing structure and a supporting rib, and the conformal antenna is of a flexible structure and is arranged on the inner surface of the metamaterial antenna housing and / or the outer surface of the supporting rib; the multi-path reflection wave-absorbing structure, the metamaterial antenna housing and the supporting ribs are assembled together to form the low-scattering airborne aperture structure. According to the low-scattering airborne aperture structure, the problem that a strong scattering source is easily formed by an airborne aperture in related technologies can be solved, and the effect of effectively reducing the scattering magnitude of the airborne aperture is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of airborne communication design, and in particular, relate to a low-scattering airborne aperture structure. Background technique [0002] Airborne aperture is an important tool for airborne communication, but with the improvement of low-scattering requirements of aircraft, aperture design is often a prominent problem in low-scattering design. Firstly, the airborne apertures are often arranged in the direct radiation area of ​​detection radar waves, usually without shielding; secondly, the apertures are usually installed in the cavity structure of the aircraft, and cavity scattering is the most important source of scattering; meanwhile, due to the aperture structure, jump Due to the wiring layout and other reasons, the structural scattering of the airborne aperture is increased, thereby forming a strong scattering source through the amplification of the cavity.
