Sea Echoes for Airborne HF/VHF Radar: Mathematical Model and Simulation

open access: yesRemote Sensing, 2020
Currently, shore-based HF radars are widely used for coastal observations, and airborne radars are utilized for monitoring the ocean with a relatively large coverage offshore.

Wave and tidal power measurement using HF radar

open access: yesInternational Marine Energy Journal, 2018
The use of HF radar systems located on the coast to measure ocean surface waves and currents is reviewed. Examples are given showing temporal, spatial and directional variability in the wave and tidal power resource. HF radars are unique in being able to

Coverage Area Analysis of Combined Sky-Wave and Surface-Wave Monostatic High Frequency Radar

open access: yesIEEE Access, 2019
High-frequency combined sky-wave and surface-wave monostatic radar (CSSM-HF RADAR) is a new type of radar system inspired by the skywave components of high-frequency surface-wave radar (HFSWR). The new type of radar uses the combined propagation paths of

Wave power measurements in the Celtic Sea using HF radar [PDF]

open access: yes, 2017
: It is well established that HF radar systems located on the coast can measure surface currents from close to the coast to more than 100km offshore. They can also be used to simultaneously measure the ocean wave directional spectrum.

Miniaturisation of high-frequency SURFACE wave radar transmitting antenna

open access: yesThe Journal of Engineering, 2019
Antennas operating in the high-frequency (HF) bands are generally relatively large in size, which severely limits the application of the antennas. Therefore, miniaturisation of the antenna is necessary.

Sea Storm Analysis: Evaluation of Multiannual Wave Parameters Retrieved from HF Radar and Wave Model

open access: yesRemote Sensing, 2022
Intense atmospheric disturbances, which impact directly on the sea surface causing a significant increase in wave height and sometimes strong storm surges, have become increasingly frequent in recent years in the Mediterranean Sea, producing extreme ...

Wind-induced drift of objects at sea: the leeway field method [PDF]

open access: yes, 2011
A method for conducting leeway field experiments to establish the drift properties of small objects (0.1-25 m) is described. The objective is to define a standardized and unambiguous procedure for condensing the drift properties down to a set of ...
