A logical basis for nested array data structures
Computer Languages, 1989Abstract 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 ...

Underwater DoA estimation based on nested array
MILCOM 2015 - 2015 IEEE Military Communications Conference, 2015This paper generalizes a new algorithm for Direction of Arrival (DoA) estimation in one and two dimensional (1D and 2D) underwater non-uniform sensor array networks (UWSANs). The extension of augmented matrix approach from the minimum redundancy array (MRA) to the nested array and co-prime array is the main issue addressed in this work.

Nested arrays, operators, and functions
Proceedings of the international conference on APL - APL '81, 1981Although 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.

Distributed source processing with linear nested arrays
2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014We 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 ...

DOA Estimation Method with the Distributed Nested Array
2018 10th International Conference on Wireless Communications and Signal Processing (WCSP), 2018In 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
2004Construction 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.

The nested rectangular array as a model of data
Proceedings of the international conference on APL: part 1 - APL '79, 1979Data, like electricity and gravity, are part of the world in which we live. Some occur naturally, as in the genetic code, while most occur as a consequence of language and social organization. The search for a theory of data, which begins with the choice of a model, is as important and interesting as the development of theories in physics, economics ...
