A robust model-based source localization (MBSL) scheme for 3D positioning of high-frequency underwater acoustic (UWA) transmitters, as well as performance assessment of 3D speed vector estimation of the acoustic source, deploying two linear receiver arrays, is developed and evaluated. In addition, this paper presents the sensitivity evaluation of MBSL to uncertainties involved in environmental parameters,...
The problem of inferring side information regarding an underwater acoustic (UWA) channel from the environmental signature imprinted on waveforms by the propagation medium, particularly the transmitter/receiver configuration and relative speed vector, is addressed in this paper. The main contribution of this work is to develop techniques to automatically deal with wavefront classification, i.e., to...
Localization of underwater acoustic (UWA) sources using observed signals is a popular research topic that has many potential applications, both military and civilian (e.g., navigation of underwater vehicles, mine hunting, marine mammal studies). This work adopts an inverse problem framework where the temporal and spatial structure of multipath observed at an array of sensors deployed in an ocean waveguide...
