| Summary: | Tropospheric ducts, characterized by anomalous positive vertical refractive index gradients, significantly influence radio wave propagation by enhancing signal strength and extending communication ranges. While beneficial in some contexts, these phenomena can disrupt communication systems, particularly in maritime and coastal regions where ducting conditions are prevalent. This paper addresses the challenge of accurately predicting and mitigating the effects of tropospheric ducts on radio propagation, which is critical for the reliability of next-generation communication systems. We present a comprehensive review of radio propagation in tropospheric ducts, encompassing fundamental concepts, theoretical models, and estimation techniques. To enhance the classification of anomalous propagation in the troposphere, including ducting, we develop machine learning models based on real-world data obtained from King Fahd University of Petroleum and Minerals (KFUPM). Our findings demonstrate that machine learning models, particularly support vector machines, can effectively classify ducting conditions, offering superior predictive performance compared to other models. The advancements presented in this paper address the challenges faced by next-generation radio systems and contribute to the development of effective mitigation strategies. The insights gained pave the way for further research and optimization of communication system performance in duct-prone environments. |
