“…The application scenarios are classified as near to the sea surface (mainly for ship communications [25]) and hundreds of meters above the sea surface (mainly for airborne maritime applications), depending on the transceiver altitude. Our studies show that the sea-surface reflection is an important contribution for over-sea radio-wave propagations, and its effect is very obvious for near sea-surface applications.…”

This paper presents some key considerations for modeling of over-sea radio-wave propagations in 5 GHz band. The summarized information is based on a series of measurement campaigns which were recently carried out in the tropical maritime environments near Singapore. Multiray propagations and ducting of radio waves have been highlighted and considered in over-sea path loss modeling and prediction. It is noted that the sea-surface reflection is an important contribution in the received field, while the duct layers could enhance the radio-wave propagations. Our studies also show that the refracted ray inside evaporation duct could be a strong ray for short-range near sea-surface applications and needs to be properly evaluated.

“…It has been demonstrated that the S-band is heavily encumbered by shipborne, airborne, and ground-based military radar systems in the U.S. [31] due to its less susceptibility to atmospheric attenuation. The 5 GHz band has been proven to have good potential for military applications [32], such as off-shore anti-terrorist surveillance or the application of unmanned surface vehicles (USVs) in the maritime environment. And the X-band is preferred for a sharper image and better resolution [33].…”

Precision modeling of radar signal behavior in maritime environments holds paramount importance in ensuring the robust functionality of maritime radar systems. This work delves into the intricate dynamics of radar signal propagation in maritime environments, with a particular focus on the effects of falling rain. A theoretical model encompassing raindrop scattering, gaseous absorption, and ocean surface backscattering was developed and validated. Key findings reveal that rain significantly alters radar backscattering, with a noticeable decrease in signal strength under higher rainrates. Additionally, gaseous absorption, particularly at elevated frequencies and humidity levels, emerged as a critical factor. The study also highlights the complex interplay between wind-induced ocean surface roughness and radar signal behavior. We think these insights are pivotal for enhancing maritime radar system accuracy, particularly in adverse weather conditions, and paving the way for future research in refining environmental impact models on radar signals.

“…Still the value is for reference purpose for cell planning, since inconsistencies could be found between different set of measurements as the case in [40], in which reported RMS delay spread value occasionally slumps at the greater distance.…”
