Array signal processing

2001
In this chapter, an overview of the fundamentals of array signal processing is provided with a particular emphasis on recent advances in direction-ofarrival (DOA) estimation and adaptive beamforming. It is then highlighted that the signal models used in array processing and space-time block coded MIMO communications are rather similar. At the same time,

Signal Eigenvector Method For General Array Signal Processing

SPIE Proceedings, 1988
A high resolution algorithm is presented for resolving multiple incoherent and coherent plane waves incident on an array of sensors. The incident sources may be a mixture of narrowband and broadband sources, and, the array's geometry is unrestricted. This algorithm makes use of a fundamental property associated with the signal eigenvectors of the array'

Processing Spatiotemporal Signals Recorded Linear Array

2020 1st International Conference Problems of Informatics, Electronics, and Radio Engineering (PIERE), 2020
The paper proposes and describes an algorithm for processing signals with a random initial phase, which are fed to the elements of a linear digital antenna array, in the presence of internal noise and external interference. The algorithm is based on the mathematical description of signals and active interference as multidimensional spatiotemporal ...

Array processing for wideband biological signals

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992
In this paper we present array processing techniques used to discriminate between propagating wideband biological signals. Velocity and frequency responses for a circular array designed to enhance nerve signal from a desired direction while rejecting myoelectric signal from any direction are presented.

Applications of Array Signal Processing

2014
Abstract Array Signal Processing (ASP) refers to the collection and manipulation of data obtained from multiple spatially distributed sensors or antennas, in an effort to extract information about the sources of signals present in the data. As discussed in this chapter, such problems arise in many different fields, including radar, sonar, medicine ...

Array Signal Processing for Radio Astronomy

Experimental Astronomy, 2004
Radio astronomy forms an interesting application area for array signal processing techniques. Current synthesis imaging telescopes consist of a small number of identical dishes, which track a fixed patch in the sky and produce estimates of the time-varying spatial covariance matrix.

ACOUSTIC TRANSDUCER ARRAY SIGNAL PROCESSING

The Journal of the Acoustical Society of America, 2012
A set of filters is configured to distribute input signals representing a single perceptual axis to first and second physically separate arrays (10OL, 100R) of loudspeakers comprising at least first and second transducers (104, 106, 108, 110), such that the arrays of loudspeakers will create an array pattern corresponding to the input signals when the ...

Array signal processing using digital subarrays

IET International Conference on Radar Systems 2007, 2007
Subarrays constitute a step in the direction towards full digitisation of array antennas. An overview of the problems of digital processing with subarray outputs and a description of several mitigation techniques is given. We present rules for designing subarrays, for forming sum and difference beams, clusters of scanned beams at subarray level, and ...

On Performance of Array Signal Processing

IEEE Journal of Oceanic Engineering, 1987
A unified treatment for performance evaluation of various array signal processors is presented. Detection performance is expressed in terms of the parameter of the power-type receiver operating characteristic (ROC) for optimum, beamformer, and null-steerer detectors.
