Key words: acoustics, propagation, scattering, beamforming, turbulence, random media, tomography, sound, modeling

Research opportunities are available to study sound propagation in the atmosphere. We are particularly interested in:

• the effects of atmospheric turbulence on signal variability, detection and beamforming, using both theoretical and experimental approaches
• three-dimensional tomography of the atmosphere
• modeling of sound propagation and scattering in urban terrain, atmospheric turbulence, and the forest and other complex terrains
• propagation modeling on high-performance computational platforms
• finite-differences time-domain modeling
• nocturnal propagation modeling and data analysis
• remote sensing of the atmosphere
• advanced processing techniques for tracking sources in realistic atmospheric environments.

Computational facilities and experimental sites are available.
