A Multi-Feature Visibility Processing Algorithm for Radio Interferometric Imaging on Next-Generation Telescopes
By
Progress In Electromagnetics Research C, Vol. 52, 39-52, 2014
Abstract
The visibility distribution, which is related to the configuration of stations, can be categorized into different features, each having different levels of data number density. A computationally efficient multi-feature image reconstruction algorithm, well adapted for next-generation telescopes, is proposed based on this observation, which is more flexible to handle massive amount of visibility data expected in the future. In reconstructing the M87 image with the visibility data simulated on the Low-Frequency Array (LOFAR), this algorithm turns out to be a few hundreds to one thousand times faster and is more resilient to noises than the conventional algorithms.
