Abstract: Focusing on the problem of underwater acoustic bionic communication signal recognition, a recognition method based on autocorrelation function is proposed in this paper, which takes the ...

Abstract: This paper proposes an integrated time-frequency rate distribution (TFRD) technique, i.e., coherently integrated trilinear autocorrelation function (CITAF), for the detection and parameter ...
