Reverberation Suppression Using Wideband Doppler-Sensitive Pulses

IEEE Journal of Oceanic Engineering, 2008
The influence of transmitted waveforms on the signal-to-reverberation ratio (SRR) of a low-frequency active sonar is analyzed both theoretically and experimentally. Reverberation experiments have been conducted during a sea trial in a littoral water environment in October 1999.

Reverberation Clutter Suppression Using 2-D Spatial Coherence Analysis

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2022
Diffuse reverberation clutter often significantly degrades the visibility of abdominal structures. Reverberation clutter acts as a temporally stationary haze that originates from the multiple scattering within the subcutaneous layers and has a narrow spatial correlation length.

Blind single-channel suppression of late reverberation based on perceptual reverberation modeling

The Journal of the Acoustical Society of America, 2011
A blind method for suppressing late reverberation from speech and audio signals is presented. The proposed technique operates both on the spectral and on the sub-band domains employing a single input channel. At first, a preliminary rough clean signal estimation is required and for this, any standard technique may be applied; however here the estimate ...
