A computer-implemented method of discriminating a surface from a subsurface sound-generating target in the water includes identifying an arrival angle of sound generated by the sound-generating target and received by a sound receiver at a known depth in the water. The method also includes generating a probability density function about the measured arrival angle having a corresponding plurality sound arrival angles and mapping the probability density function about the measured arrival angle to a probability density function of vertex depths. The method also includes calculating a probability that the depth of the sound-generating target is greater than a threshold depth by integrating the probability density function of vertex depth. A computer readable storage medium has instructions for implementing the above method and a system has modules for implementing the above method.
