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 a laboratory environment to detect the experimental process before and after the protective target camouflage installed with a metasurface as an example.

[0028] In this embodiment: select the iron flat plate with a size of 30cm*30cm as the protection target, and use the laboratory wall as the background environment, but in order to distinguish the two in the radar one-dimensional range image, the protection target is placed 5m direc...

Abstract

The present invention proposes a radar self-adaptive camouflage method based on a digitally coded metasurface. A digitally coded metasurface is installed on the surface of the protection target, and the distance between the protection target and the environmental background of the protection target is adjusted by adjusting the electromagnetic scattering amplitude of the digitally coded metasurface. The difference in electromagnetic scattering characteristics makes the electromagnetic scattering characteristics of the protective target and the environmental background of the protective target tend to be consistent, so as to realize the radar adaptive camouflage of the protective target and increase the detection cost of the enemy radar detection system. The radar camouflage method provided by the present invention can flexibly and dynamically adjust the electromagnetic scattering characteristics according to the different environments where the protected target is located, reduce the radar exposure symptoms of the protected target in a typical environmental background, and achieve the effect of radar self-adaptive camouflage, which is a radar camouflage technology. Research offers new ideas.

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...
