Reverberation suppression using non-negative matrix factorization to detect low-Doppler target with continuous wave active sonar [PDF]
EURASIP Journal on Advances in Signal Processing, 2019 In active sonar systems, the detection of echo from targets can deteriorate due to reverberation. Detection becomes more difficult if targets have low-Doppler frequency and are located near the reverberation band, especially in an environment with low ...

Linear frequency modulation reverberation suppression using difference of singular values [PDF]
The Journal of the Acoustical Society of America, 2008 This letter proposes a reverberation suppression method to improve the target detection probability in reverberation environment induced by a linear frequency modulation signal. Using the singular value decomposition and an assumption of local spatial stationarity, the proposed algorithm suppresses reverberation utilizing the difference of singular ...

Methods for reverberation suppression utilizing dual frequency band imaging [PDF]
The Journal of the Acoustical Society of America, 2013 Reverberations 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 ...

Ocean Reverberation Suppression via Matrix Completion with Sensor Failure
, 2020 In the ocean environment, reverberation is a common and strong interference which significantly degrades the performance of target bearing estimation. Meanwhile, sensor failure is inevitable in actual sonar deployment as the underwater scene is complicated. Therefore, it is a challenge for target detection in the ocean reverberation with sensor failure.
