Surface duct is a well-observed occurrence in the atmospheric airspace whereby a thin layer of airspace is formed closer to the surface, hence advancing the propagation range of electromagnetic signals. This ducting effect can improve radar and radio signal transmission, which affects communication and surveillance applications. The environmental factors at the site could affect the formation of the duct and the reliance on a specific set of modelling assumptions made with the Monterey-Miami Parabolic Equation (MMPE) approach of the ducting system. To estimate the surface ducts more effectively, the Artificial Fish Swarm Driven Dynamic Seagull Optimization (AFS-DSO) technique is employed in this study. Using several iterations, the study investigates propagation loss, objective function, convergence rate, and clutter power modelling as electromagnetic wave propagation attributes. The efficiency of the proposed AFS-DSO is found to be higher than the conventional technique of Dynamic Seagull Optimization (DSO). The results show the effectiveness of the improvement compared to the baseline using hybrid optimization algorithms, which can improve estimates of surface ducts for radar and thin film applications. |
