Assessment of High-Resolution Matched Field Processing Based on Model-GeneratedShallow-Water Acoustic Wave Fields

摘要

Power response expressions for matched field processing (MFP) take the samegeneral forms as their beamformer counterparts, but for the source localization simulations discussed herein the signal covariance matrix and sample replica vectors are formulated in terms of waveguide-attenuated complex pressures that characterize the acoustic field arriving at each array sensor. A question of interest is: among the various spatial processing algorithms and wave field models available, are there preferred combinations with regard to the optimal implementations of MFP. This paper presents comparisons of MFP results obtained using combinations of two high resolution spatial processing algorithms and three numerically diverse transmission loss models. Numerical results are presented for a modest aperture vertical line array in a shallow water waveguide. (AN).
