Abstract
Location of underwater moving target device carrying a receiver configured to detect acoustic waves emitted at a known location is estimated such that to be consistent with detected velocity and orientation of the target device, and with a current phase of a signal corresponding to the acoustic waves detected at the target device. A stack including one or more boxes obtained by applying contractors to location boxes is output as the estimate of the location of the moving target device.
