abstract = "In order to solve the problem of strong reverberation interference in the test of low-frequency echo characteristics of targets, the reverberation suppression method based on the time-space correlation characteristics of low-frequency reverberation is studied, and the real-time matching
and suppression method of reverberation based on the separation of target echo and background reverberation based on target motion is proposed. The results show that, based on the matching processing of background reverberation and target echo parameters, this method can significantly reduce
the low-frequency reverberation background in the test water area, and the reverberation in the lake test environment can be reduced by more than 10 dB, and the suppression effect is related to the correlation coefficient and phase difference of reverberation. This method has reference value
for practical engineering application.",
