Modeling Reverberation Time Series for Shallow Water Clutter Environments

Abstract

The phenomenon of clutter in shallow water environments can be modeled from several approaches. One approach we have taken is to model reverberation time series for heterogeneous environments with a variety of scattering mechanisms to compare the resulting characteristics to those of experimentally observed clutter. Here we show R-SNAP reverberation time series estimates for the Malta Plateau region in the Straits of Sicily that seem to capture some of the clutter behavior observed during the SCARAB 98 experiment conducted in conjunction with the NATO Undersea Research Centre (NURC), Italy. Of particular interest is the appearance of coherent time-frequency striation patterns in both the modeled and observed reverberation, with spatially compact, broadband clutter features superimposed by the presence of environmental discontinuities.
