Distributed source processing with linear nested arrays

2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014
We consider the problem of using linear nested arrays to estimate the direction of arrival (DOA) of spatially distributed sources and detect the source number, where we have more sources than the actual physical sensors. Angular spread, caused by the multipath nature of distributed sources, makes the commonly used point source assumption ineffective ...

A logical basis for nested array data structures

Computer Languages, 1989
Abstract A logical description of array data structures is presented as an extension of a theory of equality over lists. It provides axioms and theorems that describe the data objects of the Nested Interactive Array Language, Nial. A model for the theory is presented, and the application of the theory to the development of a logic programming ...

Nested arrays, operators, and functions

Proceedings of the international conference on APL - APL '81, 1981
Although the original ideas of nested arrays go back over ten years, it has been only within the past few years that these ideas have matured. During the same period, several new operators and functions have been proposed. This paper describes an experimental research implementation of these proposals.

DOA Estimation Method with the Distributed Nested Array

2018 10th International Conference on Wireless Communications and Signal Processing (WCSP), 2018
In this paper, we investigate the problem of direction of arrival (DOA) estimation in phased-array radar. The array consisting of two separated nested subarrays with dual baselines is used to form the DOA problem. And we present a new DOA estimation method, called weighting signal subspace MUSIC method (WSSMUSIC).

With-Loop Scalarization – Merging Nested Array Operations

2004
Construction of complex array operations by composition of more basic ones allows for abstract and concise specifications of algorithms. Unfortunately, naive compilation of such specifications leads to creation of many temporary arrays at runtime and, consequently, to poor performance characteristics.
