The Radio Array of Portable Interferometric Detectors (RAPID) is a spatially diverse sparse radio array. It has been designed to be deployed and reconfigured easily for scientific applications. These applications include both geospace and astronomy experiments where a relatively small and sparse aperture is sufficient in size. Examples include the study of ionospheric turbulence using active and p...Show More
The Radio Array of Portable Interferometric Detectors (RAPID) is an advanced radio designed for multi-role applications. The system implements a spatially diverse sparse array technology and can be deployed and reconfigured easily. Data are captured at the raw voltage level using the system in the field and processed post-experiment. Signal processing for the system is software defined and uses a ...Show More
The Murchison Widefield Array (MWA) is a new low frequency interferometric radio telescope, operating in the remote Murchison Radio Observatory in Western Australia. In this paper we present the first MWA observations of the well known radio relics in Abell 3667 (A3667) between 120 and 226 MHz. We clearly detect the radio relics in A3667 and present flux estimates and spectral indices for these fe...Show More
