Wireless sensor networks (WSNs) contain sensor nodes in enormous amount to accumulate
the information about the nearby surroundings, and this information is insignificant until the …

Imagine being in a crowded room with a cacophony of speakers and having the ability to
focus on or remove speech from a specific 2D region. This would require understanding and …

Different from the traditional approach of using the reduced set of time-difference-of-arrival
(TDOA) measurements, localization by the full TDOA set is discussed here. It avoids …

Passive localization of acoustic or radio-frequency sources is often performed using time-
difference-of-arrival (TDOA) measurements and/or frequency-difference-of-arrival (FDOA) …

The curse of outlier measurements in estimation problems is a well-known issue in a variety
of fields. Therefore, outlier removal procedures, which enables the identification of spurious …

A metal diaphragm-based omnidirectional fiber-optic acoustic sensor with high sensitivity
has been developed in this work. The acousto-optic transducer of the sensor is a single …

Measuring the time delay of arrival (TDOA) between a set of sensors is the basic setup for
many applications, such as localization or signal beamforming. This paper presents the set …

The accuracy in ranging and direction in locating a target source is crucial in sound source
localization and different methods have been proposed due to important applications of …

The problem of geolocation of a radio-frequency transmitter via time difference of arrival
(TDOA) and frequency difference of arrival (FDOA) is given as a system of polynomial …

It is desirable to enable emitter location using frequency difference of arrival (FDoA)
measurements only, since many signals are characterized by coarse range resolution and …
