Reverberation suppression using non-negative matrix factorization to detect low-Doppler target with continuous wave active sonar

Abstract 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 signal-to-reverberation ratio. In this...
