Calibrating and Beamforming Distributed Arrays in Passive Sonar Environments
(2022)This dissertation presents methods for calibrating and beamforming a distributed array for detecting and localizing sources of interest using passive sonar. Passive sonar is critical for underwater acoustic surveillance, ... -
Optimal Passive Sonar Signal Processing Using the Waveguide Invariant
(2019)This dissertation presents optimal signal processing methods and performance analysis for passive, waveguide invariant (WI)-based acoustic source range estimation in shallow water marine environments. The WI, commonly denoted ... -
Passive Ranging of Tonal Sources in Shallow Water Using the Waveguide Invariant
(2017)Shallow water, coastal regions with high volumes of shipping traffic provide an excellent opportunity to passively characterize the ocean acoustic propagation environment. In this paper, a hybrid maximum-likelihood method ...
