Study on Robust Cascaded Time-Space Adaptive Reverberation Suppressing Method

Ma Quli, Zhan Haoke, Yuan Bingcheng, and Zhu Xi
Abstract— The cascaded time-space adaptive method usually use an inverse Reverberation Covariance Matrix calculation to obtain adaptive weights. Reverberation covariance matrix is singular matrix owing to limited IID sample number obtained by active sonar in non-stationary environment. Based on which, a robust cascaded time- space adaptive method is presented in this paper. The new method uses diagonal loading and conjugate after reversal arranging data to overcome the problem of limited sample number. In the scenario of limited sample number, the new approach can cancel the reverberation effectively. The sea trial results to verify its effectiveness are presented.

Index Terms— Reverberation, space-time adaptive, diagonal loading, limited sample, reversal arranging data.
