Description

Black barrier area X-ray communication system and method thereof
Technical Field
The invention belongs to the technical field of X-ray communication, and particularly relates to a black barrier area X-ray communication system and a method thereof.
Background
When the aircraft, the satellite, the spacecraft, the space shuttle and other space reentry bodies pass through the atmosphere, huge friction and strong extrusion are generated between the aircraft, the satellite, the spacecraft, the space shuttle and other space reentry bodies and the air, when the temperature is suddenly increased to more than 3000K, atmospheric molecules are ionized, and part of electrons rotating around atomic nuclei are separated from the traction of the atomic nuclei and become free electrons, so that the originally neutral molecules become ions with positive charges. Meanwhile, when the free electrons meet with positively charged ions, the free electrons are compounded into neutral molecules, and finally, the ionization and the compounding reach an equilibrium state. In addition to the interaction of free electrons and charged ions in the gas, and physical and chemical processes such as chemical freezing of non-equilibrium ionization processes caused by fluid diffusion, surface enhancement of chemical reactions, burning of aircraft surfaces, deposition of surface net charges, etc., a plasma with a certain thickness is finally formed around the aircraft, which is called as a plasma sheath. Plasma sheath density of 109~1014Per cm3The frequency of the communication signal is higher than the frequency range (1-10 GHz) of the conventional L, S, X and C wave communication signals, so that most of the communication signals can be absorbed and reflected by the plasma, and a screen similar to a metal cover is generatedThe shadowing effect causes attenuation of communication signals, and in severe cases, leads to complete signal interruption, which is called a communication blackout phenomenon.
Communication blackouts can cause interference or interruption in the real-time transmission of the relevant signals, which can have a serious impact on the real-time control and safety of the aircraft. The blackout time usually lasts for 4-10 minutes, the aircraft may be in the worst space environment in the period, any parameter information such as impact, vibration, overload and the like cannot be transmitted to the ground command system in time, and the fault cannot be eliminated in time, so that the aircraft is disassembled, and even the life safety of astronauts is threatened. Therefore, it is important to solve the communication problem in the blackout area.
Currently, there are two types of methods for inhibiting or reducing the black barrier effect: the first method is to weaken the electron density distribution of plasma above the aircraft antenna, for example, add strong magnetic field or magnetic windowing, introduce cross electromagnetic field, purify harmful impurities of heat release materials, etc.; the second method is to improve the penetration ability of electromagnetic waves in the plasma sheath, such as increasing the transmission power, increasing the gains of the transmitting antenna and the receiving antenna, increasing the carrier frequency (using Ku and Ka band or terahertz band electromagnetic waves for communication), and the like. However, neither of the above two approaches completely solves the communication problem in black-out areas.

The X-ray communication signal generating device generates X-rays with modulation information and transmits X-ray focal spots radiated along the 4 pi direction to the X-ray communication signal receiving device 6; the method specifically comprises the following steps:
the X-ray with modulation information generated by the high-frequency X-ray generation modulator 3 is transmitted to the X-ray collimating lens 4 through the X-ray focal spot 10, and forms a parallel X-ray beam with modulation information through the X-ray collimating lens 4, as shown in fig. 3, the X-ray beam with modulation information is radiated to the X-ray focusing lens 7 through the X-ray focal spot radiated by 4 pi through the X-ray collimating lens 4, and then is focused on the X-ray demodulator 8.
Wherein, the two ends of the first cathode filament binding post 31 and the second cathode filament binding post 32 are electrified, when the temperature of the cathode filament 33 reaches above 800 ℃, the free electron beam 40 is generated;
