Description

TECHNICAL FIELD

[0002] At present, atmospheric ionization can be generated in many ways. In addition to photoionization, high-energy particles are also the main cause of ionization generation. Under the condition of high-energy particle injection, high-energy particles will interact with neutral atmospheric molecules to cause atmospheric ionization to form an "additional ionization zone". When the radio wave propagation passes through the additional ionization zone, the collision effect will be significantly enhanced, causing a large amount of collision loss to the radio wave propagation.

[0003] However, the current theoretical model involves less quantitative analysis of the collision loss effect of radio wave propagation through the additional ionization zone. Therefore, there is an urgent need for a new method to evaluate the collision loss effect under the condition of high-energy particle injection and to establish a communication effect evaluation model of the additional ionization zone. This is of great significance for accurately evaluating the propagation loss effect of the additional ionization zone on the radio wave or for constructing a communication link based on the additional ionization zone.
