“…The array aperture of 26cm can accurately estimate the narrow-band sound source of 600Hz [9]. Professor Yang Desen of China developed two kinds of 8-element vector circular arrays for barrier conditions and free field environment, derived the preprocessing matrix of sound pressure and particle vibration velocity based on the sound field decomposition theory, and then constructed the covariance matrix of sound pressure and vibration velocity, and realized Angle estimation by applying various beamforming methods [10].…”

Vector hydrophone is a new type of underwater acoustic sensor, which is one of the hot spots in the field of underwater acoustic technology in the 21st century. In order to explore the feasibility of vector hydrophone circumferential array in engineering applications, a 16-yuan composite vector hydrophone circumferential array is designed and manufactured in this paper. The array diameter is 1.92m and the working frequency band is 20~3000Hz. The experimental results show that the array has better target azimuth estimation ability than scalar circular array.

“…Acoustic vector sensors (AVSs) can simultaneously measure the acoustic pressure as well as two or three orthogonal particle velocity components at a single spatial point [2][3][4][5][6][7][8][9]. As the AVS can make use of the extra available acoustic particle velocity information, the arrays composed of AVSs have some attractive advantages compared to the pressure sensor arrays with the same configuration, such as higher spatial gain [10], stronger ability to suppress noise [11], lower direction-of-arrival (DOA) estimation error [3,12], etc. Owing to the above advantages, the measurement of the radiated noise by using the acoustic vector-sensor array (AVSA) has attracted broad attention.…”

In this work, we design a small-sized bi-cone acoustic vector-sensor array (BCAVSA) and propose a frequency invariant beamforming method for the BCAVSA, inspired by the Ormia ochracea’s coupling ears and harmonic nesting. First, we design a BCAVSA using several sets of cylindrical acoustic vector-sensor arrays (AVSAs), which are used as a guide to construct the constant beamwidth beamformer. Due to the mechanical coupling system of the Ormia ochracea’s two ears, the phase and amplitude differences of acoustic signals at the bilateral tympanal membranes are magnified. To obtain a virtual BCAVSA with larger interelement distances, we then extend the coupling magnified system into the BCAVSA by deriving the expression of the coupling magnified matrix for the BCAVSA and providing the selecting method of coupled parameters for fitting the underwater signal frequency. Finally, the frequency invariant beamforming method is developed to acquire the constant beamwidth pattern in the three-dimensional plane by deriving several sets of the frequency weighted coefficients for the different cylindrical AVSAs. Simulation results show that this method achieves a narrower mainlobe width compared to the original BCAVSA. This method has lower sidelobes and a narrower mainlobe width compared to the coupling magnified bi-cone pressure sensor array.
