Acoustic Vector-Sensor FFH "Blind" Beamforming & Geolocation

IEEE Transactions on Aerospace and Electronic Systems, 2010

An acoustic direction-finding and blind interference rejection algorithm for up to three noncooperative wideband, fast frequency-hop (FFH) spread spectrum signals of unknown hop sequences and unknown arrival angles is presented. This algorithm avoids the need to adjust beamforming weights to accommodate frequency variations in the frequency-hopping signals. This approach deploys one acoustic vector-sensor (a.k.a. vector-hydrophone), which is composed of two ...


Recursive Least-Squares Source Tracking using One Acoustic Vector Sensor

IEEE Transactions on Aerospace and Electronic Systems, 2012

An acoustic vector-sensor (a.k.a. vector-hydrophone) is composed of three acoustic velocity-sensors, plus a collocated pressure-sensor, all collocated in space. The velocity-sensors are identical, but orthogonally oriented, each measuring a different Cartesian component of the three-dimensional particle- velocity field. This acoustic vector-sensor offers an azimuth-elevation response that is invariant with respect to the source's center frequency or bandwidth. This acoustic vector-sensor ...

An acoustic vector-sensor (a.k.a. vector-hydrophone in underwater applications) is composed of two or three spatially collocated but orthogonally oriented acoustic velocity-sensors, plus possibly a collocated acoustic pressure-sensor. An acoustic vector-sensor is versatile for direction-finding, due to its azimuth- elevation spatial response's independence from the incident source's frequency, bandwidth, or radial location (i.e., in the near field as opposed to the ...


Acoustic Near-Field Source-Localization by Two Passive Anchor-Nodes

IEEE Transactions on Aerospace and Electronic Systems, 2012

A new scheme is herein proposed to localize an acoustic source. This new method blends the "received signal strength indication" (RSSI) approach of geolocation, and the acoustic vector-sensor (AVS) (a.k.a., vector-hydrophone) based direction-finding (DF). Unlike customary RSSI-based source-localization, this proposed approach needs only two (not three or more) passive anchor- nodes: 1) one pressure-sensor, and 2) one physically compact triad ...

  • Measurements of Waves and Current in Support of Coastal Projects on Nantucket and Martha's Vineyard

    MAVS acoustic velocity sensors have been deployed in the surf zone at Madaket beach, Nantucket and on a dock piling at Oak Bluffs, Martha's vineyard since mid-winter of 2006. Power is supplied to each instrument through a dedicated cable connection and data are returned through this tether to PCs for logging. The current meters report velocity, pressure, temperature, and turbidity in real-time to support continuous monitoring of wave and sediment conditions as they impact beach processes or velocity and pressure for wave conditions in support of marine construction.

  • Acoustic Vector-Sensor FFH "Blind" Beamforming & Geolocation

    An acoustic direction-finding and blind interference rejection algorithm for up to three noncooperative wideband, fast frequency-hop (FFH) spread spectrum signals of unknown hop sequences and unknown arrival angles is presented. This algorithm avoids the need to adjust beamforming weights to accommodate frequency variations in the frequency-hopping signals. This approach deploys one acoustic vector-sensor (a.k.a. vector-hydrophone), which is composed of two or three spatially collocated, but orthogonally oriented, acoustic velocity-sensors plus an optional collocated pressure-sensor. The spatial collocation of all component sensors comprising such an acoustic vector-sensor frees the beamforming weights of any dependence on the signals' hopping frequencies.

  • Recursive Least-Squares Source Tracking using One Acoustic Vector Sensor

    An acoustic vector-sensor (a.k.a. vector-hydrophone) is composed of three acoustic velocity-sensors, plus a collocated pressure-sensor, all collocated in space. The velocity-sensors are identical, but orthogonally oriented, each measuring a different Cartesian component of the three-dimensional particle- velocity field. This acoustic vector-sensor offers an azimuth-elevation response that is invariant with respect to the source's center frequency or bandwidth. This acoustic vector-sensor is adopted here for recursive least- squares (RLS) adaptation, to track a single mobile source, in the absence of any multipath fading and any directional interference. A formula is derived to preset the RLS forgetting factor, based on the prior knowledge of only the incident signal power, the incident source's spatial random walk variance, and the additive noise power. The work presented here further advances a multiple- forgetting-factor (MFF) version of the RLS adaptive tracking algorithm, that requires no prior knowledge of these aforementioned source statistics or noise statistics. Monte Carlo simulations demonstrate the tracking performance and computational load of the proposed algorithms.

  • Cramér-Rao Bounds for direction finding by an acoustic vector-sensor under unknown gain / phase uncertainties

    An acoustic vector-sensor (a.k.a. vector-hydrophone in underwater applications) is composed of two or three spatially collocated but orthogonally oriented acoustic velocity-sensors, plus possibly a collocated acoustic pressure-sensor. An acoustic vector-sensor is versatile for direction-finding, due to its azimuth- elevation spatial response's independence from the incident source's frequency, bandwidth, or radial location (i.e., in the near field as opposed to the far field). Unavailable in the current open literature is how the direction-of-arrival (DOA) estimates may be adversely affected by any unknown non-ideality in the acoustic vector- sensor. The non-ideality may include any unknown deviation from the nominal gain response and/or phase response. This paper pioneers a characterization of these various unknown non-idealities' relative degradation on direction- finding accuracy through Cramer-Rao Bound (CRB) analysis of how the estimation accuracy is degraded relatively by each such unknown non-ideality.

  • Acoustic Near-Field Source-Localization by Two Passive Anchor-Nodes

    A new scheme is herein proposed to localize an acoustic source. This new method blends the "received signal strength indication" (RSSI) approach of geolocation, and the acoustic vector-sensor (AVS) (a.k.a., vector-hydrophone) based direction-finding (DF). Unlike customary RSSI-based source-localization, this proposed approach needs only two (not three or more) passive anchor- nodes: 1) one pressure-sensor, and 2) one physically compact triad of three (collocating, but orthogonally oriented) acoustic velocity-sensors. The latter can estimate the direction-of-arrival (DOA) of an emitter, regardless of that emitter's arbitrary/unknown center-frequency, bandwidth, spectrum, and near- field/far-field location. This triad's DOA estimates can be "distributed processed," locally, apart from the pressure-sensor's measured power, to estimate the emitter's radial distance. This proposed algorithm is noniterative, requires no initial estimate, is closed form, and can accommodate any prior known propagation-loss exponent.

  • Sensor fouling prevention in an acoustic current meter, MAVS

    Coatings to inhibit attachment of marine organisms to sensors were applied to acoustic velocity sensors and tested for seven months in near-surface waters in Woods Hole, Massachusetts and found to effectively prevent attachment of fouling organisms to substrates of ABS plastic, epoxy, urethane, and to a lesser degree to stainless steel. This treatment was effective longer than biocides generally have been in these conditions. The material in the coatings, silicone in some form, prevents the organisms from getting a tight grip and they either do not manage to settle or are washed off by natural low- velocity currents and waves in the mooring field in Eel Pond harbor.
