    • Adaptive near-field beamforming techniques for sound source imaging 

      Cho, Yong Thung; Roan, Michael J. (Acoustical Society of America, 2009-02-01)
      Phased array signal processing techniques such as beamforming have a long history in applications such as sonar for detection and localization of far-field sound sources. Two sometimes competing challenges arise in any ...
    • Multiple-array passive acoustic source localization in urban environments 

      Mennitt, Daniel; Johnson, Marty E. (Acoustical Society of America, 2010-05-01)
      In many situations of interest, obstacles to acoustic wave propagation such as terrain or buildings exist that provide unique challenges to localization. These obstacles introduce multiple propagation paths, reflections, ...
    • Non-linear, adaptive array processing for acoustic interference suppression 

      Hoppe, Elizabeth A.; Roan, Michael J. (Acoustical Society of America, 2009-06-01)
      A method is introduced where blind source separation of acoustical sources is combined with spatial processing to remove non-Gaussian, broadband interferers from space-time displays such as bearing track recorder displays. ...
