Problems solved by technology

However, the existing RCS enhancement technology often cannot realize the adjustable design of RCS enhancement, or the controllable range of RCS enhancement is small, and the degree of freedom of regulation is insufficient.
[0003] Therefore, designing a system that can intelligently and dynamically regulate RCS is very important for dynamically simulating the real electromagnetic environment and saving simulation costs, and solve the problem that the existing Longbo lens reflector cannot realize RCS active regulation

Abstract

The invention discloses an active metasurface-based intelligent RCS (radar cross section) adjustable luneberg lens system, which relates to the technical field of antennas and comprises an active frequency selective surface, a luneberg lens, an active wave-absorbing metasurface and an intelligent control system, the intelligent control system can regulate and control the size of the RCS in a wide angular domain and the RCS enhancement angular domain by regulating and controlling the states of all active devices loaded on the active frequency selective surface and the active wave-absorbing metasurface or in a specific angular domain. The invention has the advantages of high integration level, modular design, batch production, good controllability and broadband response, and can be used for the dynamic regulation and control of the RCS size in the target wide angular domain and the dynamic regulation and control of any RCS enhanced angular domain.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an intelligent RCS tunable Lumbo lens system based on an active metasurface. Background technique [0002] Radar cross section (RadarCross section, RCS for short) is an attribute of weaponry. RCS enhancements can be used both for target drones to simulate enemy airstrike weapons, and for our false target settings. However, the existing RCS enhancement technologies often cannot realize the controllable design of RCS enhancement, or the controllable range of RCS enhancement is small, and the degree of freedom of regulation is insufficient. [0003] Therefore, it is very important to design a system that can intelligently and dynamically control the RCS to dynamically simulate the real electromagnetic environment and save the simulation cost. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide an intelligent RCS tunable Lumbo lens system based o...
