Abstract

This work offers a new synergy of the Received Signal Strength Indication (RSSI) approach of source-localization and the acoustic vector-sensor (a.k.a., vector-hydrophone). The (spatially spread) acoustic vector-sensor consists of three identical and colocated velocity-sensors, plus one pressure-sensor at some (known) distance away from the velocity-sensor triad. The velocity-sensor triad itself can estimate an incident source's azimuth-elevation angle, but not the source's radial distance from the triad. The pressure-sensor's measured power and the triad's measured power together can estimate the incident source's radial distance. This proposed scheme is closed-form and noniterative, requiring no initial estimates. However, this scheme can allow only one incident source, which must emit with constant power.
