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

International audience; Source parameters estimation ? mainly range and depth ? is a constant focus in the frame of oceanic propagation. Within different scenarios, the case of Ultra Low Frequency (ULF i.e. below 100Hz) signal received by an Horizont

International audience; We present here an experimental protocol to reproduce the effects of linear internal waves (LIW) on acoustic wave propagation in a very controlled and reproducible manner. In fact, the experiment consists in propagating an ult

International audience; The authors focus on the effects of phenomena, such as linear internal waves, that are responsible for fluctuations of the depth-dependent sound speed profile and, hence, induce distortions of the resulting acoustic pressure f
