LOFAR - Opening up a new window on the Universe
LOFAR, the Low Frequency Array, is a next-generation radio telescope that is being built in Northern Europe and expected to be fully operational at the end of this decade. It will operate at frequencies from 15 to 240 MHz (corresponding to wavelengths of 20 to 1.2 m). Its superb sensitivity, high angular resolution, large field of view and flexible spectroscopic capabilities will represent a dr...
متن کاملSpatial filtering of interfering signals at the 3 initial Low Frequency Array ( LOFAR ) phased 4 array test station
10 [1] The Low Frequency Array (LOFAR) is a radio telescope currently being designed. Its 11 targeted observational frequency window lies in the range of 10–250 MHz. In frequency 12 bands in which there is interference, the sensitivity of LOFAR can be enhanced by 13 interference mitigation techniques. In this paper we demonstrate spatial filtering 14 capabilities at the LOFAR initial test stati...
متن کاملLOFAR: The potential for solar and space weather studies
The Low Frequency array (LOFAR) will be a next generation digital aperture synthesis radio telescope covering the frequency range from 10 to 240MHz. The instrument will feature full polarisation and multi-beaming capability, and is currently in its design phase. This work highlights the solar, heliospheric and space weather applications where LOFAR, with its unique and unprecedented capabilitie...
متن کاملAmsterdam–ASTRON radio transient facility and analysis centre: towards a 24× 7, all-sky monitor for the low-frequency array (LOFAR)
The Amsterdam–ASTRON Radio Transient Facility And Analysis Centre (AARTFAAC) project aims to implement an all-sky monitor (ASM), using the lowfrequency array (LOFAR) telescope. It will enable real-time, 24 × 7 monitoring for low-frequency radio transients over most of the sky locally visible to the LOFAR at time scales ranging from seconds to several days, and rapid triggering of follow-up obse...
