Problems solved by technology

First of all, traditional electromagnetic pulse protection materials are difficult to apply to radar antenna equipment. No matter what material is used, it will affect the normal operation of the radar antenna and affect the signal transmission and reception of the antenna.
Secondly, in general, in order to achieve infrared stealth, it is necessary to add metal powder to the material, but the increase in the content of metal powder will inevitably reduce the radar stealth performance of the coating

Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific embodiment:

[0020] Such as Figure 1-6 As shown, it includes a plasma cloaking layer 1 and a photonic crystal cloaking film 2, and the photonic crystal cloaking film 2 is pasted on the plasma cloaking layer 1, figure 1 Reference numeral 3 in represents a stealth target, and an arrow represents a radar detection signal.

[0021] figure 2 A schematic diagram of the structure of the plasma electromagnetic pulse shielding layer is given. The plasma electromagnetic pulse protection layer is composed of a number of cylindrical dielectric tubes with a diameter of 2 to 4 cm, whose length is determined according to the size of the application object, and filled with rare gases (He, Ne, Ar, Kr, Xe) or Hg vapor according to certain rules. constitute. An alternating voltage is applied to both ends of the dielectric tube to cause the gas to break down to form a columnar plasma, and the electron...

Abstract

The invention relates to an infrared stealth structure with electromagnetic pulse protection capability. The infrared stealth structure comprises a plasma electromagnetic pulse protection layer and aphotonic crystal stealth film; the photonic crystal stealth film is attached to the plasma electromagnetic pulse protection layer; electromagnetic pulse protection is achieved through the plasma layer, and far-infrared band stealth is achieved through the photonic crystal. The plasma electromagnetic pulse protection layer is formed by arranging and combining a plurality of cylindrical dielectric tubes; alternating voltage is applied to the two ends of each dielectric tube, so that gas is broken down to form columnar plasma; the alternating voltage adjusting range of the two ends of each dielectric tube ranges from 200 V to 300 V, the frequency ranges from about 40 kHz to 100 kHz, and the plasma density in each dielectric tube is 1.0*1017 / m <3>-1.0*1019 / m <3>. The stealth structure providedby the invention has good infrared stealth performance, and can also realize effective protection of strong electromagnetic pulses.

Description

technical field [0001] The invention relates to the technical field of military stealth, in particular to an infrared stealth structure with electromagnetic pulse protection capability. Background technique [0002] With the development of infrared reconnaissance and precision guidance technology, once a military target is exposed, it often means being attacked. In order to improve the battlefield survivability of military targets, effective infrared stealth measures must be taken. At the same time, due to the gradual use of electromagnetic pulse weapons, their damage to electronic equipment cannot be ignored. [0003] However, conventional techniques have obvious deficiencies. First of all, traditional electromagnetic pulse protection materials are difficult to apply to radar antenna equipment. No matter what material is used, it will affect the normal operation of the radar antenna and affect the signal transmission and reception of the antenna. Secondly, in general, in...
