Study on robust space-time adaptive reverberation suppressing

Reverberation covariance matrix is singular matrix owing to limited sample obtained by active sonar in non-stationarity environment. Based on which, a robust space-time adaptive method is presented in this paper. The new method avoids singular matrix which aroused by small eigenvalue with diagonal loading. In the scenario of limited sample number, the new approache can cancel the reverberation effectively. The sea trial results to verify its effectiveness are presented.
