Depth Discrimination and Range Estimation of Multiple Sources in Shallow Waters

Abstract

To develop wave-oriented phase coherent signal processing algorithms (which address and incorporate the physics of acoustic wavefield propagation through and scattering from an inhomogeneous, noisy, time varying, and stochastic ocean environment) to characterize targets and the environment for applications in both passive and active systems. To validate a new and practical system concept and to develop new wave-oriented phase coherent inversion algorithms for classifying and localizing multiple sources in noisy and time-varying shallow waters without knowing the sound speed profiles. The approaches should be able to adapt (self-optimize) in the face of changing environmental and system conditions.
