Brazilian Decimetric Array (BDA) project - Phase II

A new strategy for array optimization applied to brazilian decimetric array

Radio interferometric arrays measure the Fourier transform of the sky brightness distribution in a finite set of points that are determined by the cross-correlation of different pairs of antennas of the array. The sky brightness distribution is reconstructed by the inverse Fourier transform of the sampled visibilities. The quality of the reconstructed images strongly depends on the array config...

Phased array antenna using MEMS phase shifter

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...

Solar Images Processing in Parallel Environment

This paper presents the PVA-BDA project (Processing, Visualization and Analysis in Parallel Environment of the BDA Data) that has been developed for processing of solar images that will be captured by the BDA (Brazilian Decimetric Array), a radio telescope under development at the National Institute for Space Research (INPE). In a joint effort between the Department of Computer Science at Feder...

Bda=ml + Cc

Although the term Big Data has become popular, there is no general consensus about what it really means. Often, many professional data analysts would imply the process of Extraction, Transformation and Load (ETL) for large datasets as the connotation of Big Data. A popular description of Big Data is based on three attributes of data: volume, velocity, and variety (or 3Vs). Nevertheless, it does...
