Signal Subspace Extraction Algorithm for Detection in the Presence of Reverberation

摘要：

A new algorithm called Signal Subspace Extraction is presented for detecting and estimating the target echo in reverberation.The new algorithm maintains the bene-fit of the Principal Component Inverse algorithm,moreover shows better performance with a more reasonable reverberation model.Further,a block forward matrix is proposed to extend the algorithm to the space-time array problem.The new algorithm also allows good echo separation.Examples are presented using both real,activesonar data and simulated data.
