Underwater soundscapes are complex as they are a combination of several components with overlapping acoustic frequencies and different timescales, from individual durations to seasonality and long-term trends. Sounds below 100 Hz are of particular in

The study presents an underwater acoustic signal processing approach for the identification of the material of an object using wideband chirp pulses. The echo from the target is formed by a number of processes that occur during reflection of the puls

This paper presents classification of spherical objects with different physical properties. The classification is based on the energy distribution in wideband pulses that have been scattered from objects. The echo is represented in Time-Frequency Dom
