The paper presents a practical Doppler estimator to be used in underwater acoustic (UWA) channels. The estimation is performed using OFDM pilot signals. The OFDM pilot signals are passed through a Doppler channel that adds the above effects to the signal. The receiver then performs Doppler estimation on the signal. The estimator finds an estimate for the Doppler scaling factor (also called the mach...
The proposed paper introduces a novel method for range estimation of acoustic sources, both cetaceans and industrial sources, in deep sea environments using supervised learning with neural networks in the contex of a single sensor, a compact array, or a small aperture towed array. The presented results have potential both for industrial impact and for the conservation and density estimation of cetaceans...
Many changes are occurring in the physical, chemistry and biology processes of the ocean. Understanding how these changes are driven is an element of the key environmental descriptors identified by the European Marine Strategy Framework Directive (MSFD) with the ultimate goal being to protect the resource base upon which marine-related economic and social activities depend. The Directive furthers...
