Nonlinear filtering techniques have been shown to provide good performance for pattern recognition applications. In this paper, we apply these techniques to active sonar processing and show improved performance of target echo ranging in highly reverberant environments. We propose an algorithm that eliminates the need for range and azimuthal data normalization after the matched filter by scaling the input signal prior to matched filtering.
