An electrically regulated multi-band compatible intelligent camouflage structure

Abstract

The invention relates to an electronically regulated multi-band compatible intelligent camouflage structure, comprising: an active frequency selective surface wave absorbing body and a flexible infrared compatible electrochromic device arranged thereon. Active frequency selective surface absorber, the Ю-type double-layer controllable frequency selective surface is introduced into the multi-layer absorbing layers of different loss types, and active devices such as varactor diodes are used to flexibly control the active frequency selective surface absorber. The resonant frequency is beneficial to widen its working bandwidth and realize the strong absorbing performance of microwave broadband. The flexible infrared compatible electrochromic device is coated with a photonic crystal layer on the bottom surface of the light-transmitting electrode. The structure of the photonic crystal layer is [AB] n B[AB] n The center-doped photonic crystal film structure can realize infrared and laser compatible stealth. The electronically regulated multi-band compatible intelligent camouflage structure of the present invention exerts the synergistic effect of the smart material and the metamaterial, and can realize the multi-band compatible stealth function of infrared, laser, radar and visible light.

Description

technical field [0001] The invention belongs to the technical field of stealth, and in particular relates to an electronically regulated multi-band compatible intelligent camouflage structure. Background technique [0002] Stealth technology is an important means to avoid destruction and achieve raids, and it is one of the high-tech weapons and equipment in the world. Most of the existing stealth technologies are only effective for single-band detection methods, but they cannot simultaneously cope with the current advanced precision guidance and detection technologies using radar, laser, infrared, hyperspectral and other means of joint detection. In addition, most of the existing stealth technologies belong to static camouflage, which can play a good concealment and camouflage effect in a specific battlefield background environment, but cannot adapt to different multi-domain complex background changes during the equipment maneuvering process. Therefore, static stealth Techn...

Problems solved by technology

However, traditional stealth materials and stealth structures are difficult to form new breakthroughs in the two directions of multi-spectrum compatible stealth and adaptive stealth.

[0004] At present, multi-spectrum compatible stealth of radar, infrared and visible light can be realized to a certain extent through special structural design and material compounding methods, but most of them are in the stage of basic experimental research, and the compatibility effect is not good
