Holographic array processing using short arrays
Proceedings of OCEANS '93, 2002The holographic array processing (HAP) algorithm calibrates the integrated effect of the medium between a reference (virtual) array, near the source, and the receiving array. The effect of truncating both the receiving and virtual arrays on the performance of the HAP algorithm is investigated.

Sonar Arrays and Array Processing
AIP Conference Proceedings, 2005Arrays of hydrophones have been part of Navy sonar systems for over fifty years now. They are used both passively and actively and now are quite sophisticated. These arrays were used in fixed configuration such as the SOSUS system and towed arrays deployed from surface ships and submarines.

Non-Integer Arrays for Array Signal Processing
IEEE Transactions on Signal Processing, 2022Linear arrays with sensors at integer locations are widely used in array signal processing. This paper considers arrays where sensor locations can be rational numbers. It is demonstrated that such rational arrays have some important advantages over integer arrays.

Metalens-array–based high-dimensional and multiphoton quantum source
Science, 2020Metalens-array–based quantum source Spontaneous down-conversion is an exotic optical process in a nonlinear crystal in which a high-energy photon splits into two lower-energy photons that are quantum mechanically entangled.

Array processing on an array processor
ACM SIGPLAN Notices, 1975Central memory is distributed across several processing elements on the ILLIAC-IV and similar array processors. This causes memory to appear two dimensional and raises special problems in the handling of arrays. Assignment of arrays to storage, and development of efficient array mapping functions and accessing techniques are all much more difficult ...

ARRAY RESEARCH ARRAY PROCESSING AT UBO
1967Abstract : The purpose of this study was to determine the amount of predictable noise at Uinta Basin Seismological Observatory (UBO) by the development and application of noise prediction filters. A comparison of the surface and the 200-ft buried array was conducted to determine if a large amount of noise was present which attenuates rapidly with depth.

We present a new model of parallel computation called the "array processing machine" or APM. The APM was designed to closely model the architecture of existing vector- and array processors, and to provide a suitable unifying framework for the complexity theory of parallel combinatorial and numerical algorithms.

Nonexhaustive array processing
The Journal of the Acoustical Society of America, 2003Modern arrays may contain of order a thousand elements and the subsequent beamforming requires searching over frequencies, beam angle, source–receiver range, source depth, array depth, array tilt, and array bow. The search space, easily on the order of a trillion cells, suggests seeking alternative approaches to the traditional exhaustive methods. Here

Array signal processing (ASP) represents a class of antenna system where the output from an array is subjected to various forms of signal processing (e.g. phase and amplitude control, time delay or frequency translation) in order to produce outputs which can simultaneously provide angular information relating to several different directions.

Acoustic vector sensor array processing
[1992] Conference Record of the Twenty-Sixth Asilomar Conference on Signals, Systems & Computers, 1994An approach is proposed for localization of acoustic sources using an array of sensors for which the measurement of each sensor is a vector consisting of the acoustic pressure and acoustic particle velocity. A compact expression is derived for the Cramer-Rao bound (CRB) on the estimation errors of the source direction-of-arrival (DOA) parameters in the
