Measurement and Analysis of High-Frequency Scattering Statistics and Sound Speed Dispersion

Abstract

The long-term goal of the present high-frequency scattering statistics work is to link the high-frequency reverberation envelope distribution to measurable seafloor geoacoustic properties in conjunction with sonar system parameters (such as frequency and resolution cell size), providing the foundation necessary for solving several problems related to the detection of targets in non-Rayleigh clutter. A direct link between system and environmental parameters via scattering models to the statistical distribution of reverberation will allow: performance prediction for different systems based on seafloor properties, extrapolation of performance to other system/bandwidths, and optimization of system parameters such as frequency/bandwidth to the local environment.
