Embodiment Construction

[0026] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] In this embodiment, the present invention and the technical effects that can be produced by the present invention are described in detail by taking the X-band radar in the laboratory environment to detect the experimental process before and after the protective target camouflage installed with the metasurface as an example.

[0028] In this embodiment, an iron flat piece with a size of 30cm*30cm is selected as the protection target, and the laboratory wall is used as the background environment, but in order to distinguish the two in the radar one-dimensional range image, the protection target is pla...

Abstract

The invention provides a radar adaptive camouflage method based on a digital coding metasurface. A digital coding metasurface is installed on the surface of a protection target; an electromagnetic scattering characteristic difference between the protection target and an environment background where the protection target is located is adjusted by adjusting electromagnetic scattering amplitude of the digital coding metasurface, so that the electromagnetic scattering characteristics of the protection target and the environment background where the protection target is located tend to be consistent, radar self-adaptive camouflage of the protection target is achieved, and the detection cost of an enemy radar detection system is improved. According to the radar camouflage method provided by theinvention, the electromagnetic scattering characteristics can be flexibly and dynamically adjusted according to different environments where the protection target is located, radar exposure symptoms of the protection target under a typical environment background are reduced, a radar self-adaptive camouflage effect is achieved, and a novel thought is provided for the radar camouflage technology research.

Description

technical field [0001] The invention belongs to the technical field of radar camouflage, and specifically relates to a method of adjusting electromagnetic scattering characteristics, so that the electromagnetic scattering characteristics of the protection target and the background environment tend to be consistent, and reduce the radar exposure symptoms of the protection target in a typical environment background, so as to achieve radar self-adaptive camouflage Methods. Background technique [0002] Radar is a sensor that can acquire long-distance target information autonomously, all-weather, and all-weather. It is an indispensable means of detection in modern military development. With the continuous improvement of modern radar detection capabilities, our high-value military targets are facing a great risk of exposure. In order to avoid the serious threat posed by enemy radars to our high-value military targets, radar camouflage technology for high-value targets on the batt...
