Frame®

Wind turbines can cause radar interference, showing up on radar operator’s screens as clutter, obscuring the display and resulting in lost aircraft tracking. In many instances, these wind farms are refused planning permission resulting in costly delays.

As part of its ongoing commitment to supporting the renewable energy sector, Frame® radar absorbing material has been developed to provide an innovative solution that mitigates wind turbine radar interference problems, unlocking gigawatts of new potential wind farm sites.

Frame®, is a unique radar absorbing material for the wind industry, designed to offer a full mitigation solution for tower, nacelle and blades. Recognizing that many wind farms are situated near multiple radar stations, Frame provides outstanding multi-band radar absorption, allowing a single, simple solution for a complex problem.  

The frequency of absorption can be tuned between 1-12 GHz, with an absorption bandwidth (below -20 dB) of 0.2 GHz, providing solutions for all radar types from L to X-band.

The Frame® range has been developed to functionalize blade resins and fiberglass systems to enable integrated radar absorption to make a truly robust stealth wind blade.

Due to the unique fillers used in Frame®, the product has been designed to keep the turbine weight to a minimum, providing maximum efficiency to the operator.

By using an easy to install ‘fit-and-forget’ material solution rather than radar hardware or software workarounds, the cost to the developer is kept to a minimum.
