Innovative Signal Processing Techniques for Mitigation of Wind Turbine Farm Interference in Airborne Radar Systems

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. TSCs 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.
