Using the Decomposition-Based Multi-Objective Evolutionary Algorithm with Adaptive Neighborhood Sizes and Dynamic Constraint Strategies to Retrieve Atmospheric Ducts [PDF]
Sensors, 2020 The traditional method of retrieving atmospheric ducts is to use the special sensor of weather balloons or rocket soundings to obtain information intelligently, and it is very expensive. Today, with the development of technology, it is very convenient to

Experimental Analysis of Atmospheric Ducts and Navigation Radar Over-the-Horizon Detection
Remote Sensing, 2022 Since the height of sea detection radar antenna and ship targets is relatively low, it is generally believed that its over-the-horizon detection is mainly caused by the evaporation duct at sea.

A Sliced Parabolic Equation Method to Characterize Maritime Radio Propagation [PDF]
Sensors, 2023 For maritime broadband communications, atmospheric ducts can enable beyond line-of-sight communications or cause severe interference. Due to the strong spatial–temporal variability of atmospheric conditions in near-shore areas, atmospheric ducts have ...

The detectable double atmospheric ducts for RFC [PDF]
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014 Refractivity from clutter (RFC) systems are defined for retrieving the atmospheric ducts from the sea clutter echo of a radar in open sea or coastal environment. However, some ducts hardly have an effect on the clutter echo. Consequently, the RFC technique suffers inherent limitations and is unable to provide information about these ducts.

Low-Level Atmospheric Ducts [PDF]
Nature, 1949 IN a communication in Nature1, I suggested an explanation for the occurrence of low-level atmospheric ducts over the sea, which had been reported by McPetrie and Starkey2 in conditions of strong winds. It was suggested that the previous history of the air was the governing factor in deciding whether an atmospheric duct would occur. I am indebted to Dr.
