Abstract
By matching, or correlating, a complex-demodulated (envelope) time series measured at a single hydrophone receiver to predicted envelope response functions obtained by back propagation using a full-physics broadband PE model, it is possible to remove multipath distortion effects and to determine the location of the source of an acoustic transient with good resolution and high processing gain. This ‘‘semi-coherent’’ broadband matched-field processing (BMFP) technique is demonstrated in several deep water and shallow water situations. [Work supported by ONR and ARPA.]
