Embodiment Construction

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the present invention. scope.

[0035] As mentioned above, existing radar stealth technologies such as shape stealth technology, wave-absorbing material technology, and impedance loading stealth technology mainly reduce the radar cross-section of the target by changing the amplitude and phase of the radar echo signal to achieve the effect of stealth. It can only have the function of s...

Abstract

The invention provides a radar stealth device, a radar stealth system and a radar stealth method. The radar stealth device comprises a negative bias layer and a plasma generator. The negative bias layer is arranged on a target surface layer and is used for forming a negative voltage electric field; an outlet of the plasma generator is arranged in the side, away from the target, of the negative bias layer and used for emitting plasmas in the direction away from the target, and free electrons in the plasmas do directional movement under the action of the negative voltage electric field to form a plasma layer. And the plasma layer is used for modulating the echo frequency of the radar out of the receiving frequency band of the radar. According to the scheme, the stealth frequency band can be effectively widened.

Description

technical field [0001] Embodiments of the present invention relate to the field of electromagnetic technology, and in particular to a radar stealth device, system and radar stealth method. Background technique [0002] Due to the widespread use of radar in the modern military, it has become an important detection tool. Radar stealth has naturally become an important stealth technology. The existing radar stealth technology mainly reduces the radar cross section (Radar Cross section, RCS) of the target by changing the amplitude and phase of the radar echo signal to achieve the effect of stealth. Commonly used technical measures include: shape stealth technology, absorbing materials technology and impedance loading stealth technology, etc. However, these existing technologies all have the problem of narrow stealth frequency bands. Contents of the invention [0003] Based on the problem of narrow stealth frequency band in the prior art, embodiments of the present invention...
