dc.description.abstractThe development of an algorithm for extended towed-array measurements, which could be used by matched-field estimators to obtain information about depth and range of a source, is studied. This algorithm combines coherently the acoustic signal arrivals at a moving hydrophone towed array by making proper compensation through a phase correction factor for considerable fluctuations in phase, irregularities in the tow path of the physical array, as well as in amplitude during the coherent
dc.description.abstractintegration time. The concept of the extended towed-array processing is based on what we call overlapped correlator, which provides the phase correction factor by correlating overlapping space samples of the acoustic signal received at successive moments in time by the moving towed array.
dc.description.abstractThe algorithm has been applied on numerical data generated by the SNAP normal mode model. The
dc.description.abstracteffects of space and time coherence of the signal and the random and systematic errors on the
