An adaptive reconfigurable intelligent radar radome system
By using an adaptive reconfigurable intelligent radar radome system, the electromagnetic metasurface is fed by a signal source, a power divider, and a phase shifter. This achieves electromagnetic shielding and high-transmittance switching within the same frequency band, solving the problem of electromagnetic shielding and protection that cannot be achieved in the full frequency band in existing technologies. This results in efficient electromagnetic protection and signal transmission.

Abstract
The application provides an adaptive reconfigurable intelligent radar radome system, which can realize adaptive bidirectional band-pass high transmission for any radar signal when the radar works, and realize full-band shielding when the radar does not work, so that electromagnetic protection and electromagnetic stealth of the radar are maximized. According to the principle of generalized Fresnel law, by increasing active feeding on the electromagnetic super surface, the surface current density of the electromagnetic structure can be adaptively changed according to the passing radar signal, so that the band-pass characteristic without transition frequency band at any frequency point and any bandwidth can be realized. The application solves the problems that the traditional frequency selective surface cannot realize full-band shielding when the radar does not work, and cannot adaptively realize the band-pass of the same frequency as the radar signal when the radar works, and can be applied in the field of intelligent stealth of the radar radome.
