Radar and Telecommunications

Radar Assessment

Where potential wind turbine and radar conflict exists, it is vital to identify as early as possible any potential issues that may stop your wind project from progressing. Radar interference is a potential development stopper and can often lead to conflict due to its impact on relevant licensed aerodromes, unlicensed airfields, radio navigation aids and meteorological radar.

Neo can help with differing levels of radar assessment, they include:

  • Simple Aviation Assessment – This will highlight all aviation assets which a wind turbine could potentially impact upon. It will come in a couple of page report and basically identify the aviation assets and the potential blade tip height which will be acceptable.
  • Full Technical Assessment – This will come in the form of an in depth report and will be suitable to submit with a planning application.  Line of sight calculation charts and diagrams will supplement the report enable you to clearly see how much of a wind turbine is visible to a single radar installation; our line of sight calculations take into account earth curvature and diffraction.
Telecommunications and Electromagnetic Interference

Fixed microwave links require a clear line of sight between the transmitting and receiving antennae and wind turbines placed in close proximity to the path of a link may impair its operation. Ultra High Frequency (UHF) telemetry and telecontrol links do not always operate with clear line of sight; wind turbines placed in close proximity to the path of a telemetry and telecontrol link may impair their operation. Television Re-Broadcast Links transfer television signals between transmitters; wind turbines placed in close proximity to the path of those links may impair their operation. Terrestrial television services are provided by means of UHF radio waves which propagate from transmitters to receiving aerials which then relay the signal to a television (TV) set; the operation of wind turbines can adversely affect domestic television reception. Consultation with the relevant operators may be necessary. Often interference can be minimised or eliminated through a combination of appropriate turbine siting and special technical solutions.
