PSIBED - Parametric Structures for Integrative Backscatter models and Environmental Database

Understanding shallow underwater environment is increasingly important, but shallow water acoustic models depend on a large number of factors that interact in a non-linear fashion. There are many different acoustic back scatter models, but many of the models haven’t changed in years and some of the new ones rely on stochastic methods. What’s needed is a general acoustic model and environmental parameter structure that can parameterize existing models and associated environmental data, as well as act as a new acoustic modeling framework for shallow underwater environmental awareness. 21st Century Systems, Incorporated is pleased to introduce our parametric structure for integrative bottom backscatter models and environmental database (PSIBED…pronounced “seabed”). PSIBED develops a parametric space built on powerful geometric algebraic formalism for generalizing backscatter models as advanced layered sediment algebraic “versors.” The PSIBED algebraic signatures are used to describe and integrate models with parameters and environmental databases. PSIBED uses a multi-dimensional Clifford Fourier Transform structure for representing complex underwater environments and handles propagation of uncertainty as a first class property of PSIBED. Preliminary experiments reveal the potential to obtain, store, and utilize acoustic bottom backscatter information. This technology will ultimately lead to better underwater systems for use by manned and unmanned systems.
