Ocean reverberation suppressing by direct data domain based STAP
2012 IEEE 11th International Conference on Signal Processing, 2012A class of direct data domain based space time adaptive processing (STAP) method for ocean reverberation suppressing is studied. The original direct data domain least square (D3LS) STAP does not use statistical information of the testing snapshot. This work proposes a new method named direct that the snapshot number has no effect on the performance of ...

Reverberation characterization and suppression by means of principal components
IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259), 2002We apply the principal component inverse (PCI) method of rapidly adaptive interference suppression to the problem of separating the strong components of reverberation in an active reverberation experiment. A best low-rank estimate of a reverberation return is extracted by decomposing the returns into short duration subintervals over which the signal is

The bottom reverberation suppression algorithm for side scan sonar
2014 Oceans - St. John's, 2014The sea bottom reverberation is one of the important problems, which restrict the bottom targets detection performance with the high frequency imaging sonar. In this paper, a bottom reverberation suppression algorithm is presented to improve the performance of the high frequency side scan sonar for small target detection.

Broadband DOA Estimation by Beamforming with Suppression of Reverberation
2008 Congress on Image and Signal Processing, 2008Acoustic signal processing in shallow water environments is a challenging problem because of the presence of reverberation. Based on some models of reverberation, data from sensors array is pretreated to suppress reverberation. Considering reverberation as a sum of echoes of transmitted signal, the principal component inverse (PCI) algorithm is ...

Reverberation characterization and suppression by means of principal components
The Journal of the Acoustical Society of America, 1994A method of reverberation suppression and characterization, called the principal components inverse (PCI) method, has been used to separate strong components of the reverberation from the observed data of an active sonar reverberation experiment. The number of principal reverberation components needed to represent these strong components seldom exceeds
