Passive source localization is a crucial issue in underwater acoustics. In this paper, we focus on shallow water environment (0 to 400 m) and broadband Ultra-Low Frequency acoustic sources (1 to 100 Hz). In this configuration and at a long range, the

Sperm whale clicks, which are nonstationary broadband transients, are analyzed using the normalized recursive exact least-square time-variant lattice filter. The results are compared with those obtained using the classical techniques of energy detect

This article presents the results using a parametric approach and a Wavelet Transform in analysing signals emitting from the sperm whale. The extraction of intrinsic characteristics of these unique signals emitted by marine mammals is still at presen

International audience; The common use of the bent-horn model of the sperm whale sound generator describes sperm whale clicks as the pulse series {p0, p1, p2, p3, . . . }. Clicks, however, deviate from this standard when recorded using off-axis hydro

International audience; Sperm whales generate transient sounds (clicks) when foraging. These clicks have been described as echolocation sounds, a result of having measured the source level and the directionality of these signals and having extrapolat

The paper proposes a new effective analytic signal representation dedicated to underwater signal analysis. The proposed approach is based on the recursive normalized exact least-square ladder estimation algorithm because of its excellent convergence

This paper proposes a non-stationary time-series segmentation method based on the analysis of the forward prediction error issued from the adaptive Schur orthogonal signal parameterisation. There is no a priori information about the analysed signal t
