Abstract. In underwater acoustics, the requirement for “high-resolution” (HR) bearing estimation is often accompanied by the availability of only short-time data records; such conditions arise naturally in passive systems when high bearing-rate sources are being observed, or in active systems when, at most, only a few echoes are by: 1.

Year: The spatial processing methods already discussed are applicable to the active problem so that in this section we emphasize the temporal aspects of active signal processing.

Active Sonar Signal Processing The basic elements of an active sonar are: the (waveform) transmitter, the channel through which the signal, echo and interference. Dr Salah Bourennane received his PhD degree from Institut National Polytechnique de Grenoble, France.

An underwater acoustic communication channel simulator has been developed to model transmission of a continuous spectrum communication signal () within the nominal bandwidth of 8 kHz to 16 kHz sampled at 96 kS/s, to generate an output pressure signal () at 96 kS/s. Sparse (t,f) distributions are then applied to geophysics acoustics (Section ) and a concise tutorial review of (t,f) audio processing for speech and underwater acoustics applications indicates that high-resolution TFDs can result in much improved performance (Section ).

Acoustics is the primary method for remote sensing of the underwater environment because sound can propagate over much greater underwater distances than electromagnetic waves can.

Since roughly 70% of the world's surface is covered by ocean water, acoustics is typically necessary to probe the majority of the Earth's ecosystems, and the majority.
