Scatter Channels and Target Modeling for Active Signal Extraction in Underwater Acoustics: 2. Summary and Synthesis of 1, [1]

Abstract

The purpose of this document is to provide a review and synthesis of the author's recent detailed analyses of scatter channels and target models for the active threshold detection of underwater targets in an ocean environment [1]. The summary and synthesis describe the main results of analytic modeling of: (1) Generalized scatter (reverberation) channels; (2) Line target models, with bistatic orientation and doppler; (3) Threshold detection algorithms for the mixed gauss, non-gauss ambient and reverberation noise; (4) The detection parameter governing performance for these dominant signal-dependent noise milieux. In addition to the general canonical treatment, the results provide a framework for signal (i.e., waveform) design to maximize further the expected performance. A short list of next steps in the analytic program is included, along with selected references.
