Reverberation Suppression Algorithm for Obstacle Avoidance Sonar Based on Sparse Decomposition
2026 International Conference on Image, Signal Processing and Pattern Recognition (ISPP)When active sonar is used in shallow-water environments, its performance is significantly affected by reverberation, which leads to degraded detection capabilities due to a low signal-to-reverberation ratio. To address this challenge, this paper proposes

Methods for reverberation suppression utilizing dual frequency band imaging
The Journal of the Acoustical Society of America, 2013Reverberations impair the contrast resolution of diagnostic ultrasound images. Tissue harmonic imaging is a common method to reduce these artifacts, but does not remove all reverberations. Dual frequency band imaging (DBI), utilizing a low frequency pulse which manipulates propagation of the high frequency imaging pulse, has been proposed earlier for ...

Late Reverberation Suppression Using Recurrent Neural Networks with Long Short-Term Memory
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2018Human speech is usually distorted by room reverberation. These corruptions degrade speech quality and intelligibility, especially under a long reverberation time, and they also pose a serious problem for many speech-related applications such as automatic

Adaptive Reverberation Suppression Techniques for SHM in Composite Materials
Structural Health Monitoring 2015, 2015This paper introduces a new method for Structural Health Monitoring using error functions computed from guided waves reflected from damage. The approach is experimentally tested on anisotropic specimens such as composite plates. The baseline and test signals of each sensing path (between two PZT transducers) are measured and the energy of the scattered

In shallow water environments, reverberation, which is generated from the rough seabed, remains one of the major sources of background interference in active sonar systems. This paper proposes a reverberation suppression method that leverages multidimensional property differences, designed for a rough seabed.
