What is the NEXRAD Program doing to solve the WTC problem?
REPLY: The NEXRAD Program has provided research funds to the Univ of Oklahoma to devise potential short-term and long-term solutions. Short-term efforts are focusing on automatic identification and flagging of wind turbine-corrupted data. Advanced signal processing techniques, such as non-stationary clutter filtering, are also being explored as sophisticated and robust solutions, but these are long-term efforts. In addition, innovative radar designs, such as adaptive phased array antennas, are being explored as potential solutions. Finally, knowledge-based techniques, which would exploit information (blade phase, rotation speed, etc.) from wind turbines are being conceived. The Atmospheric Radar Research Center (ARRC) at the University of Oklahoma plans to make use of its Electromagnetic Microphysics Laboratory (EML) for this final concept. With the appropriate funding stream, experiments could be conducted to simulate a working turbine within the lab, providing the ability to test kno
