Ionosphere detection system based on magnetized plasma incoherent scattering theoretical spectrum

Abstract

The invention belongs to the technical field of ionosphere detection, particularly relates to an ionosphere detection system based on a magnetized plasma incoherent scattering theory spectrum, and aims to solve the problem in the prior art that the ionosphere state cannot be accurately detected under different conditions. The system comprises an input module which acquires an ionosphere initial incoherent scattering theoretical spectrum; a model selection instruction module which generates a model selection instruction; an incoherent scattering theory spectrum module which pre-constructs an incoherent scattering theory spectrum model, performs model solving under different conditions to obtain each incoherent scattering theory spectrum sub-model, and obtains an ionosphere radar echo powerspectrum through the corresponding sub-model based on the ionosphere initial incoherent scattering theory spectrum and the model selection instruction; and an output module which extracts ionosphere state, motion, structure and disturbance information based on the ionosphere radar echo power spectrum and outputs the information. Different ionosphere conditions correspond to different sub-models, and the ionosphere information under different conditions can be accurately and quickly detected.

Description

technical field [0001] The invention belongs to the technical field of ionospheric detection, and in particular relates to an ionospheric detection system based on the theoretical spectrum of magnetized plasma incoherent scattering. Background technique [0002] The ionosphere is an area of ​​the earth's atmosphere with a height range of about 60-100 km. Because it contains a large number of free electrons, it is equivalent to a plasma conductor, and electromagnetic signals will interact when propagating in it. When the signal frequency is below a specific frequency, it will be reflected at the ionosphere; when the signal frequency is above this specific frequency, the signal will pass through the ionosphere and be refracted by the ionosphere at the same time, thus changing the direction of propagation. The higher the frequency of the signal, the less the propagation path is bent due to ionospheric refraction. Therefore, any electronic system that relies on radio waves to c...
