Abstract
This invention relates to a hybrid waveguide inversion method based on microwave path loss. By establishing a point-to-point microwave link, employing multiple transmitting and receiving antennas at various altitudes, multiple monitoring frequencies, and multiple monitoring locations, and combining system parameters, the path loss of microwave propagation at different antenna altitudes, frequencies, and distances along the link is calculated. Then, a hybrid waveguide profile is established on the link. Using electromagnetic wave propagation models, objective functions, and optimization algorithms, a hybrid waveguide profile including surface waveguides and evaporating waveguides is obtained. This method acquires multiple hybrid waveguide profiles, improving the performance evaluation accuracy of marine electromagnetic systems and enabling the inversion of hybrid profile characteristics of evaporating waveguides and surface waveguides.
