Wave Measurement Validation
We have published a new paper on wave measurement validation including single radar inversions and spectral partitions.
Published in Remote Sensing, part of the special issue HF Surface Wave Radar: Improving Performance and Extending Capabilities. [ doi ]
Presentation
Oceans2023
Lucy presented a paper on 'HF radar wind, wave and current measurements for offshore wind power' at the recent Oceans2023 conference in Limerick, Ireland.
Chapter contribution
Swell and wind-sea
Partitioning is a process used to separate wind-sea and swell contributions in an ocean wave directional spectrum to simplify, and hence make more useful, the interpretation of the spectrum for users of wave data.
In this paper: Swell and wind-sea partitioning of HF radar directional spectra we describe a partitioning method applied to HF radar directional spectra measurements obtained using our Seaview Sensing software and show the resulting maps of separated swell and wind wave parameters.
Chapter contribution
Machine Learning
Current measurements using HF radar systems are widely used. We have also demonstrated wave and wind direction measurements with good accuracy.
Methods to obtain wind speed have been suggested by a few authors but so far not been sufficiently accurate.
We have been working on a new approach using machine learning and a first paper on this has just been published in Remote Sensing doi.

Lucy has had a new paper published: 'Spatio-Temporal Metocean Measurements for Offshore Wind Power'
It is available online and for download.
New Publication
inversion of bistatic radar data
Lucy and colleagues at the University of Sheffield have published a paper on the inversion of bistatic radar data
Remote Sens. 2020, 12, 313 doi
Seaview Sensing software was modified to carry out the inversions but the modification is not yet part of our operational software package. Until this has been implemented we can only process small amounts of bistatic data in house.
If you would like us to process your bistatic data do get in touch.

Presentation
Lucy and Andrew recently attended the Radiowave Oceanography Workshop (ROW) 2019 in Victoria, Canada, where Lucy presented 'New Approaches to wave measurement' which included results from the InnovateUK dual frequency tests and new bistatic results linked to Rachael Hardman's PhD thesis.
Lucy also gave a lecture on 'Wave measurement using HF radar' at International Summer School On Radio Oceanography 2019 which preceded ROW.
Presentation
Developments in metocean HF radar technology
Lucy presented a paper "Developments in metocean HF radar technology, application and accuracy" at the recent OMAE2019 conference in Glasgow.
This reported on the work we did with Neptune Radar and Swansea University partially funded by InnovateUK showing that simultaneous dual frequency operation has a positive impact on wave measurement accuracy.
Publication June 2019
Lucy has contributed to a paper "The Global High Frequency Radar Network" recently published in Frontiers in Marine Science doi.
This is an overview of HF radar activities around the world.
