The problem of underwater Finger localization is a crucial part of the underwater pipeline monitoring and maintenance by using an AUV in oil and gas industries. In this problem, a Finger repeatedly transmits pulses of audio signals to an array of hydrophones. Due to the delay pattern, the direction of a Finger relative to the hydrophone array can be estimated. However, since underwater environment...
The estimation of the position of an emitting source is an important aspect of emerging cognitive radio systems. We readdress the known problem of estimating the Direction-of-Arrival (DOA) of an emitting source via passive radio means, namely an antenna array. The challenges in the considered scenarios are (a) time-varying, terrestrial multipath propagation with medium-to-low SNR and (b) very short...
