Abstract

Detection processing of the Toroidal Volume Search Sonar beamformer output prior to image formation is used to increase the signal-to-reverberation. The energy detector and sliding matched filter perform adequately at close range but degrade considerably when the reverberation begins to dominate. The skewness matched filter offers some improvement. A dispersion based reconditioning algorithm, introduced in this paper, is shown to provide considerably improvement in the signal-to-reverberation at far range.
