Query: Matched shadow processing   Traditional matched field processing is based on the comparison of the
complex amplitudes of the measured and calculated wave fields at the aperture
of the receiving antenna. This paper considers an alternative approach based on
comparing the intensity distributions of these fields in the "depth -- arrival
angle" plane. To construct these intensities, the formalism of coherent states
borrowed from quantum mechanics is used. The main advantage of the approach
under consideration is its low sensitivity to the inevitable inaccuracy of an
environmental model used in calculation.
