Sonar array signal processing for sparse linear arrays

ISSPA '99. Proceedings of the Fifth International Symposium on Signal Processing and its Applications (IEEE Cat. No.99EX359), 2003
Acoustic signals which propagate through the ocean have wavefronts which can differ significantly from the "planar wavefronts" assumed in array signal processing. In this paper we investigate the performance of the the minimum variance distortionless response (MVDR) beamformer and the previously introduced Fourier integral method (FIM), when applied to

A new method of array processing

ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
A new array processing technique is presented. This technique provides the number of incoming signals and the bearing of the signals concurrently. It makes no assumptions about the correlation between signals, and the spatial correlation properties of the sensor noise in a given array.

Array processing extensions to FORTRAN

Proceedings of the 1979 annual conference on - ACM 79, 1979
For well over a year, X3J3, the FORTRAN Standardization Subcommittee of the American National Standards Institute has been considering potential changes to FORTRAN-77. A subgroup with about six members has been meeting and considering additions to FORTRAN for array processing. This paper summarizes the state of their deliberations in August of 1979; it

Acoustic vector sensor array processing

[1992] Conference Record of the Twenty-Sixth Asilomar Conference on Signals, Systems & Computers, 1994
An 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

A Compiler for an Array and Vector Processing Language

IEEE Transactions on Software Engineering, 1985
A compiler for a Pascal-based language Actus is described. The language is suitable for the expression of the type of parallelism offered by both array and vector processors. The implementation described is for the Cray-1 computer. An objective of the implementation has been to construct an optimizing compiler which can be readily adapted for a range ...

Array processing machines: An abstract model

BIT Numerical Mathematics, 1987
We present a new model of parallel computation called the ``array processing machine'' or APM (for short). 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.

Adaptive processing array systems

Proceedings of the IEEE, 1992
Adaptive array systems have undergone enormous growth and progress in the past two decades. Because this multidiscipline technology area is both complex and mathematics intensive, it often appears alien (and perhaps impractical) to the nonspecialist. To help bridge those gaps, this tutorial paper has been and limited to just three principal topic areas:

Phased array processing for spike discrimination

Neurocomputing, 2005
We present a novel approach for the detection, discrimination, and identification of superimposed neuronal action potentials from multineuronal, multichannel extracellular nerve recordings with low signal-to-noise ratios. The approach uses phased-array processing techniques to identify the spikes from different neurons on the basis of their unique ...

An Array and List Processing System

Proceedings of ILC 2014 on 8th International Lisp Conference, 2014
We present ALPS, a personal interactive computational environment that combines the primitives and arrays of APL\360 with the syntax and semantics of early LISP. Selected features from APL\2, Scheme, Common Lisp and other extensions were incorporated over time. Both LISP and APL are among the oldest surviving programming languages.

Optimum array filters for array data signal processing

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1983
This paper deals with the design of filters for processing data obtained from arrays of sensors used for signal measurements in a variety of applications. The objective of the filters is to optimally suppress undesired signals intercepting the array, while at the same time to preserve the desired signal that the array is attempting to measure.
