Metadata: 2007, QinetiQ, North Hoyle, Assessment of visibility of North Hoyle and proposed Gwynt y Môr wind farms from neighbouring radars
Abstract:
This project was been requested by npower renewables after an objection to the Gwynt y Mor Offshore Wind Farm was lodged by NATS En-route Ltd (NERL) on the grounds of the potential impact on the St Annes radar. Airport Planning and Development Ltd (APD) were appointed to look into this and subsequently requested QinetiQ to assist in the technical part of the investigation. This report provides an assessment of visibility of both North Hoyle and proposed Gwynt y Môr wind farms from neighbouring radars. Key recommendations emphasize prioritizing the development of in-fill radar solutions and further investigating advanced technologies like phased arrays and electronic fencing to maintain safe airspace surveillance, as existing mitigation options are insufficient.

| Other details | ||
| Internal code | Internally assigned metadata identifier | 29866 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 2007, QinetiQ, North Hoyle, Assessment of visibility of North Hoyle and proposed Gwynt y Môr wind farms from neighbouring radars |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Radar assessment and radar visibility |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 7b9f01b4-cde6-42d5-a826-292225d5844a |
| Resource Identifier | This is the code assigned by the data owner. | TCE-1687 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2007-08-10 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2007-09-17 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Using technical assessments, simulations, antenna analysis, and radar modelling—including line-of-sight and coverage mapping, post-MTI RCS modelling, and comparative reviews of in-fill radar options—the studies confirmed that the wind farms would cause unacceptable radar clutter and persistent plots, with existing mitigation strategies such as screening, antenna height modification, beam-switching, and physical or electronic fencing proving either impractical or ineffective. Reviews of alternative radar coverage identified RAF Valley, Clee Hill, and Manchester Airport as the best candidates for in-fill mitigation, although all potential solutions presented limitations. |
