Distributed ElectroMagnetic Acoustic LOCalization

Real-time localization of electromagnetic/acoustics transient sources using hybrid electromagnetic-acoustic distributed sensing

(1) RF Antenna—electromagnetic detection of transient phenomena : detection and elevation localization;

(2)Acoustic Array — azimuth localization

(3)Embedded electronics: signal acquisition and conditioning + wireless data transfer.
