Configurable Detector Array Test Station

SPIE Proceedings, 1989
An advanced test station has been developed to test integrated focal plane array (FPA) hardware. This test system is intended to test readouts, sensor chip assemblies, modules, and complete FPAs. The test station was developed in response to existing and anticipated project requirements that exceed the performance capabilities of existing test stations.

A CMOS electrically configurable gate array

IEEE Journal of Solid-State Circuits, 1989
A CMOS electrically configurable gate array that combines the flexibility, efficiency, extendability, and performance of mask-programmed gate arrays with the convenience of user programmability is described. The implementation is facilitated by a novel two-terminal antifuse programmable element and a configurable interconnect technology.

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.

An architecture for electrically configurable gate arrays

IEEE Journal of Solid-State Circuits, 1989
A novel architecture for CMOS electrically configurable gate arrays using a two-terminal antifuse element is described. The architecture is extensible and can provide a level of integration comparable to mask-programmable gate arrays. This is accomplished by using a conventional gate array organization with rows of logic modules separated by wiring ...

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.

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 ...

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.

2D angle and array response estimation with arbitrary array configuration

ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 2003
Based on second-order statistics, we propose a novel method to estimate jointly the 2D angles of multiple independent sources and the corresponding array response. The method imposes no geometric constraint on the array and most of the sensors can be uncalibrated.

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 ...

Configurable Microprocessor Array for DSP Applications

2004
The configurable microprocessor array for DSP applications is proposed, in which each cell is the microprocessor with RISC architecture, represented as a soft IP-core. This IP-core is generated automatically by the special soft-core generator, which is based on the approach to optimization of a microprocessor architecture for its further implementation
