Reverberation, Sediment Acoustics, and Targets-in-the-Environment
Abstract
The long-term goal is to develop and experimentally test target scattering models as well as reverberation/sediment-acoustic models. Quantitatively assess the modeling approximations possible within the fidelity/speed requirements of Navy performance estimators/simulators. Over at least the last few decades, much of the basic research effort related to ASW has focused on low-frequency propagation (the passive problem). Meanwhile, submarine technology has forced the Navy to increase its use of (low and mid-frequency) active sonar, in which case reverberation (including clutter) limits performance. Contemporaneously, active sonar MCM efforts have extended their frequencies of operation from high down to mid-frequencies. Again, in many cases, reverberation limits performance for these MCM systems. Thus the shallow water problem of acoustic scattering from a target in a waveguide, as well as character of the associated reverberation, continues to be both an applied and basic research problem of some significance over a broad range of frequencies.
