• Abstract:
  From August to September 2003, NASA conducted an extensive measurement campaign to
  
  characterize the acoustic signal of wake vortices. A large, both spatially as well as in number of
  
  elements, phased microphone array was deployed at Denver International Airport for this effort.
  
  This paper will briefly describe the program background, the microphone array, as well as the
  
  supporting ground-truth and meteorological sensor suite. Sample results to date are then presented
  
  and discussed. It is seen that, in the frequency range processed so far, wake noise is generated
  
  predominantly from a very confined area around the cores.
