Description

Technical Field

[0001] The present application relates to the field of shortwave communication technology, for example, to a method and apparatus, detection equipment, and storage medium for evaluating propagation loss in an additional ionization zone of high-energy particles. Background Art

[0002] Atmospheric ionization can be generated in a variety of ways. In addition to photoionization, high-energy particles are also a major cause of ionization. Under conditions of high-energy particle injection, these particles interact with neutral atmospheric molecules, leading to the formation of an "additional ionization zone." When radio waves propagate through this additional ionization zone, the collision effect is significantly enhanced, causing significant collisional losses to the propagating radiation.

[0003] However, current theoretical models rarely involve quantitative analysis of the collision loss effect of radio waves passing through the additional ionization zone. Therefore, new methods are urgently needed to evaluate the collision loss effect under high-energy particle injection and establish a communication effect evaluation model for the additional ionization zone. This is of great significance for accurately evaluating the effect of the additional ionization zone on radio wave propagation loss or the construction of communication links based on the additional ionization zone.
