Microwave over-the-horizon radar utilizes the atmospheric waveguide effect to detect maritime targets from a distance.A numerical algorithm based on the parabolic equation method is used to establish a deterministic propagation model.The evaporation waveguide diagnosis model and global navigation satellite system(GNSS) low-altitude atmospheric waveguide monitoring technology are employed, and the intelligent inversion optimization algorithm is used to determine the atmospheric waveguide profile.Based on the parameters of the regional atmospheric waveguide environment and the working parameters of the radar system, the impact of atmospheric waveguides on the radar system′s detection performance is evaluated.Adaptively adjusting the radar′s operating mode in response to dynamic changes in path propagation loss, the radar system can timely respond to changes of the propagation environment, thereby the availability can be enhanced.
