Hypothetical Mine Hunting Sonar - Internal Wave Impact on Performance

Abstract

Acoustic signals exhibit continuous spatial and temporal variability when propagating through a sound speed field that is perturbed by oceanic internal waves. Acoustic systems operating in an internal wave perturbed sound speed field will exhibit performance variability. Numerical simulations are presented which quantify the impact of oceanic internal waves on the performance of a hypothetical mine hunting sonar system operating near a continental shelf break. The simulations show that signal excess probability distributions vary with target depth and range and the variability in the performance of the sonar system will be dependent on the figure of merit parameters selected for the system's operation.
