Innovative Signal Processing Techniques for Mitigation of Wind Turbine Farm Interference in Airborne Radar Systems Navy SBIR FY2014.1 Sol No.: Navy SBIR FY2014.1 Topic No.: N141-003 Topic Title: Innovative Signal Processing Techniques for Mitigation of Wind Turbine Farm Interference in Airborne Radar Systems Proposal No.: N141-003-0560 Firm: Technology Service Corporation 962 Wayne Avenue Suite 800 Silver Spring, Maryland 20910-4453 Contact: Fernando Giannella Phone: (203) 601-8328 Web Site: www.tsc.com Abstract: Technology Service Corporation (TSC) proposes to investigate and validate innovative techniques including one that was successfully applied to mitigate similar helicopter blade interference in an airborne foliage penetration radar for the US Army. TSC will heavily leverage its work in modeling the impact of wind turbine interference on Air Traffic Control and marine radars for the FAA and USCG, respectively. TSC will simulate high fidelity wind turbine interference and combine it with recorded radar data to initially test these mitigation algorithms. TSC's partner - the Space Dynamics Laboratory (SDL) of the Utah State University (USU) - will then collect radar data to validate these techniques using its Flexible SAR X- and L-band testbed. TSC and SDL have worked together many times before to successfully develop and validate advanced radar signal processing algorithms in this manner. In the Base Effort, TSC will define a radar system configuration and modes to study and investigate three promising candidate techniques. Measured radar data will then be used to refine and validate them. In the Option effort, TSC will expand the radar definition and investigate techniques applicable to more advanced multiple aperture systems. In Phase II, TSC will mature and further test the mitigation algorithms. Benefits: Signal processing techniques to mitigate wind turbine interference in Navy airborne radars will enable such radars to operate near wind farms which are proliferating around the world. This will minimize the impact of encroaching wind farms on the Navy's ability to train aviators in the use of radar, and in using radar for military missions including navigation, surveillance and attack. It will also enable Navy surveillance radars to obtain a clean and clear picture of ground activities near wind farms in operational areas including littoral regions where wind farms are being increasingly constructed. Other applications of this technology include airborne radars operated by the Air Force and Army. These mitigation techniques can also be employed in ground-based air defense radars that operate near wind farms and in shipboard radars that must operate in littoral regions where wind farms exist. Non-defense applications include Air Traffic Control radars operated by the FAA and Foreign ATC agencies. Return
