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

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

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:

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.

Optimal array processing with 3-D random arrays

ICASSP '81. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
In this paper, we derive the detection performance of an optimally beamformed 3-D random array system, assuming known Gaussian signal, noise, and interference statistics, and compare it with the performance of a conventional beamformed system. The receiver operating characteristics (ROC) are straightforward, nonlinear functions of the particular array ...

Aapl: An array processing language

1975
AAPL is a dialect of APL designed to be more amenable to compilation than the standard version of APL. The principal differences include the use of name prefixes, the ability to accept a limited character set for denoting the primitive functions, some variations and restrictions on the use of the program-branching primitive, and some additional I/O ...

Array signal processing for parametric array

2008
The aim of this thesis is to investigate the possible way to implement the array signal processing technique using the parametric array. This work focuses on the control of the beamwidth and the sidelobe of the difference frequency generated.
