The array configuration design of the Atacama Compact Array

SPIE Proceedings, 2008
The Atacama Compact Array (ACA) is an array composed of twelve 7-m dishes and four 12-m dishes. The ACA is designed for use as a part of the ALMA (Atacama Large Millimeter / Submillimeter Array) to provide high fidelity imaging capability for large extended objects.

Bent Configurations of Waveguide Slot Arrays

2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019
The slot array antenna is used for pattern- critical applications including satellite communications and radar. In most mobile communications antennas, the pattern detail at the mobile terminal is not critical because of the distributed target of a multipath propagation environment.

Configurable folded array for FIR filtering

Journal of Systems Architecture, 2008
The synthesis of configurable bit-plane processing array for FIR filtering is described in this paper. Possibilities for configuration are explored and encompassed by application of folding technique. The proposed folded architecture supports on-the-fly configuration of number of taps and coefficient length.

Spherical Array Configurations

2015
Motivated by the problem of spatial sampling of a sound field by a spherical array, Chap. 3 presented methods for sampling functions on a sphere, followed by methods for reconstructing a function from its samples. These could form the basis for computing the sound pressure on the surface of a sphere, given measurements by an array of microphones ...

Configuring Field-Programmable Robot Arrays

2011 International Conference on Reconfigurable Computing and FPGAs, 2011
Field-Programmable Robot Arrays (FPRAs) are MEMS micro-robots with programmable logic that can dock with other robots to make a larger digital structure. Each robot begins with a configuration for a motion algorithm, which is discarded after it reaches the desired target site.

Active antenna array lumped ring configuration

IEEE Transactions on Antennas and Propagation, 1998
Coupled active antenna oscillator arrays are used for power-combining at microwave and millimeter-wave frequencies. It is known that the relative phase determined by the element separation distance ultimately determines the array operational mode and, hence, far-field radiation characteristics.

Array configurations for dynamic time warping

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1984
In a previous paper an array architecture was revealed for real-time dynamic time warping. An integrated processor was designed and built for use in such an array. This paper discusses reduced arrays which allow a continuum of tradeoffs between speed and circuit complexity.

Sensor configuration in polarized antenna arrays

Proceedings of the Eighth International Symposium on Signal Processing and Its Applications, 2005., 2006
Single- and dual-polarized array configurations are often used in imaging and radar applications. In this paper, spatio-polarimetric correlation are used as a framework to evaluate the direction finding performance of dierent receiver configurations employing double-feed dual-polarized array as well as arrays of single-feed single-polarized elements ...

Array Configuration to Eliminate Grating Lobes

1989
A new configuration of ultrasound array transducers is proposed whose element boundaries interlock in a fine pattern to eliminate grating lobes from the acoustic field without using a very large number of array elements. Two dimensional acoustic fields produced by interlocking element 3.5 MHz array transducers are computer-simulated.
