The ability to detect the direction of arrival and time of arrival (DoA-ToA) of propagating signals generated by underwater sources using array of sensors is crucial for passive sensing. This is a challenging task especially for transient and impulsive signals which have similar acoustic signature. We consider these signals, received by each sensor in a sensor array over an observation period. We...
A nominally circular 2-D broadband acoustic array of 1.3-m diameter, comprising 508 sensors and associated electronics, was designed, built, and tested for ambient noise imaging (ANI) potential in Singapore waters. The system, named Remotely Operated Mobile Ambient Noise Imaging System (ROMANIS), operates over 25–85 kHz, streaming real-time data at 1.6 Gb/s over a fiber optic link. By using sensors...
