title: An improved broadband matched field processor for geoacoustic inversion (L).
abstract: The approach proposed here requires that for each parameter combination in a search space only a minimum processor value (over frequencies) be retained. Thus all frequencies considered at that point will have processor values at least as great as the final value. Consequently, (1) the frequency most sensitive to a parameter dominates the search automatically and (2) resolution has improved with major sidelobe reduction. The method is intended primarily for geoacoustic inversion methods (where the signal-to-noise levels are high).
