Lockheed Martin's TPS-77 radar mitigates interference, or ‘clutter’ commonly obscuring radar targets in and around wind farms.

The radar system will provide reliable air defence surveillance capabilities for the UK Ministry of Defence (MoD) and allow the UK to move forward with plans to install some 924 offshore wind turbines along England's east coast.

The radar will provide surveillance over five planned wind farms in the Greater Wash Strategic Area – Sheringham Shoal, Race Bank, Dudgeon, Triton Knoll and Docking Shoal – that are expected to generate more than 5.5 GW.

The TPS-77 radars' capabilities in wind field environments has been demonstrated in tests at land-based wind farms near the company's outdoor test range in Cazenovia, New York, as well as in trials with the Horns Rev offshore wind farm in the North Sea.

Lockheed Martin will deliver the TPS-77 system by November 2011.
