Abstract

The present invention provides a method, system and detection machine for detecting the atmospheric waveguide environment, wherein the method includes: emitting laser light into a simulated atmospheric environment; acquiring the laser light to irradiate aerosol particles with different radii in the simulated atmospheric environment, generating The laser detection backscattered light signal; the scattered light signal after the laser detection is analyzed to obtain the backscattering characteristics of the laser detection of the aerosol particles with different radii; The characteristic parameters of the atmospheric waveguide are obtained based on the backscattering characteristics and the change of the atmospheric refractive index. The solution of the invention utilizes the laser to detect the atmospheric waveguide environment, and the detection has high real-time performance.

Description

technical field [0001] The invention relates to the field of atmospheric environment parameter detection, in particular to a method, system and detection machine for detecting atmospheric waveguide environmental parameters. Background technique [0002] Atmospheric waveguide is an atmospheric space that can make electromagnetic waves return and propagate in a meandering manner. Atmospheric waveguide environment will allow electromagnetic waves to achieve trans-horizon transmission with a small attenuation. In the ocean environment, due to the presence of various gases and water vapor, the propagation path of electromagnetic waves is curved. Radar can detect distances that are several times the normal observation distance. The goal is to achieve beyond-horizon detection and reception. The atmospheric waveguide environment will also cause potential blind spots or weak signal phenomena in the normal coverage area of ​​microwave radar detection capabilities, and will also lead t...
