Internal Wave Impact on the Performance of a Hypothetical Mine Hunting Sonar

Abstract

Acoustic signals exhibit continuous spatial and temporal variability when propagating through a sound speed field that is perturbed by oceanic internal waves. Consequently, 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. They show the signal excess (probability of target detection) of a mine hunting sonar system will be temporally and spatially variable and dependent on: 1. the figure of merit parameters selected for the system s operation, 2. the sonar projector depth, and 3. the target depth and range.
