Single Receiver Rapid Geoacoustic Inversion in Shallow Water
The sediment density and compressional sound speed in shallow water can be estimated using a single receiver PANDA (Pop-up Ambient Noise Data Acquisition system) deployed by a small vessel, which then tows a small source, before returning to collect the PANDA. The impulse response function of the shallow water channel is estimated through deconvolution processing that can highly improve the time resolution of signal. Based on this processing, more accurate estimations of the geometry and corresponding bottom- reflecting coefficients can be achieved. The sediment density and compressional sound speed can then be estimated through optimum processing. Such geoacoustic inversion method is presented in this paper with some simulation results applicable to local waters.
