Title: Compressive sensing in acoustics and seismology
Abstract: Compressive sensing (CS) is a technique for finding sparse signal representations to underdetermined linear measurement equations. I will describe why compressive sensing has been found to be useful and then focus on a few applications in acoustics and seismics: 1) high-resolution beamforming. 2) In passive fathometry compressive sensing is used to invert for the number of sediment layer interfaces and their depths. 3) Earthquake location.
