title: Linear frequency modulation reverberation suppression using difference of singular values.
abstract: 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 values between the reference beam and the current beam of interest. Several experiments using real oceanic reverberation data justify the validity of the proposed algorithm.
