Abstract

The embodiment of the invention provides an evaporation waveguide detection device, and theevaporation waveguide detection device comprises: an environment sensing module which is used for obtaining the atmospheric pressure of a reference point in a target atmospheric environment; a laser emission module which is used for emitting target laser to the target atmospheric environment; a signal receiving module which is used for acquiring Raman backward scattering light signals with different heights, which are generated by collision between the target laser and atmospheric molecules when the target laser is transmitted in the target atmospheric environment; and a signal processing module which is used for determining the evaporation waveguide according to the Raman backward scattering light signals with different heights and the atmospheric pressure of the reference point. According to the embodiment of the invention, all-day, continuous and direct detection of the evaporation waveguide can be realized, effective signals within the full-height range of 0m to 100m can be effectively received, no detection blind area exists, and the measurement precision can be improved.

Description

technical field [0001] The invention relates to the technical field of evaporation waveguide detection, in particular to an evaporation waveguide detection device. Background technique [0002] In the marine environment, there are usually three types of atmospheric waveguides: evaporation waveguides, surface waveguides and suspended waveguides. Atmospheric waveguides will significantly change the propagation path and propagation range of electromagnetic waves, thereby affecting the effective combat performance of electronic systems such as radar, radio communication, and radio guidance. The occurrence frequency of offshore evaporation waveguide is high and the duration is long, which has a great impact on the transmission of electromagnetic waves above 3 GHz. Shipborne air defense and surveillance radars working in the C-band and X-band will be greatly affected. Among the existing evaporation waveguide detection devices, the most widely used is the passive evaporation waveg...
