This report was produced by RES - Renewable Energy Systems Ltd, it is an appraisall of Raytheon's mitigation solutions to susceptible interference caused by wind turbines affecting the fleet of primary radars used by NERL - NATS En-Route Limited.
NATS En-Route Limited (NERL) are the sole controller of civilian en-route air traffic control over the UK. Through a network of radars, radio-navigation aids and areas of restricted and controlled airspace. NERL can vector and advise instrumented aircraft that are transiting the country (i.e not taking off or landing). The fleet of primary radars in use by NERL are currently susceptible to interference caused by wind turbines, however in order to safely enable the construction of wind farms the manufacturer of the radar, Raytheon, has been commissioned to investigate mitigation solutions.
Raytheon were developing a variety of advanced mitigation techniques specifically for their en-route ASR 10 and ASR 23 radars. The techniques being investigated included Concurrent Beam Operation, Constant False Alarm Rate Processing, radial speed dependent clutter maps and improved tracking algorithms.
This report was not intended to and did not appraise other aspects of the Raytheon R&D work of which the success will not be known until formal field trials have been conducted.

Methodology
As the radar mitigation was only required for those turbines that are going to be visible to either St. Anne’s or Lowther Hill Radar, only those determined to be in direct line of sight were chosen for this assessment. From the layout proforma sent to the CAA, MoD and NERL (See Appendix 1 of report ) and the preliminary radar report [5] T4 & T6 have been chosen to look at the impact for Lowther Hill and T1, T2, T3, T4, & T6 chosen for St Anne’s. A turbine size of 180m to tip was used in all calculations as this represents, subject to refinement in the ‘engineering envelope’ work being undertaken, the tallest likely turbine that could be considered and therefore a worst case in terms of sterile zone extents. This analysis was repeated for smaller turbines where required. Terrain assessments calculated the distance from each radar to the relevant turbine locations and simple trigonometry was used to calculate the height above each turbine to the ceiling of the 0.8 degree Sterile Zone.
