Moment-Based Physical Models of Broadband Clutter due to Aggregations of Fish

Abstract

LONG-TERM GOALS: Contribute to a new understanding of what fish parameters control mid-frequency (MF; 1-10 kHz) biological clutter, including the relative influence of oceanographic phenomena; and provide benchmark data sets and statistical models for signal-processing algorithm development. These in turn will help to develop a capability to statistically forecast the impact of bioclutter on MF Navy systems. OBJECTIVES: Develop, and refine/validate with field data, broadband stochastic models of MF clutter due to aggregations of fish based on higher-order statistical measures describable in terms of physical and system parameters. Environmentally, these models would provide physics-based measures of acoustical uncertainty based on biological and oceanographic parameters.
