Coherent Time-Domain Canceling of Interference for Radio Astronomy
S. W. Ellingson, R. M. Buehrer
Radio astronomy is vulnerable to interference from a variety of anthropogenic sources. Among the many strategies for mitigation of this interference is coherent time-domain canceli…
Sidelobe Modification for Reflector Antennas by Electronically-Reconfigurable Rim Scattering
S. W. Ellingson, R. Sengupta
Dynamic modification of the pattern of a reflector antenna system traditionally requires an array of feeds. This paper presents an alternative approach in which the scattering from…
Design and characterization of the Large-Aperture Experiment to Detect the Dark Age (LEDA) radiometer systems
D. C. Price, L. J. Greenhill, A. Fialkov +24
The Large-Aperture Experiment to Detect the Dark Age (LEDA) was designed to detect the predicted O(100)mK sky-averaged absorption of the Cosmic Microwave Background by Hydrogen in…
Practical Limits in the Sensitivity-Linearity Trade-off for Radio Telescope Front Ends in the HF and VHF-low Bands
R. H. Tillman, S. W. Ellingson, J. Brendler
Radio telescope front ends must have simultaneously low noise and sufficiently-high linearity to accommodate interfering signals. Typically these are opposing design goals. For mod…
Design and Commissioning of the LWA1 Radio Telescope
S. W. Ellingson, J. Craig, J. Dowell +2
LWA1 is a new large radio telescope array operating in the frequency range 10-88 MHz, located in central New Mexico. The telescope consists of 260 pairs of dipole-type antennas who…
First Light for the First Station of the Long Wavelength Array
G. B. Taylor, S. W. Ellingson, N. E. Kassim +32
The first station of the Long Wavelength Array (LWA1) was completed in April 2011 and is currently performing observations resulting from its first call for proposals in addition t…
The LWA1 Radio Telescope
S. W. Ellingson, G. B. Taylor, J. Craig +10
LWA1 is a new radio telescope operating in the frequency range 10-88 MHz, located in central New Mexico. The telescope consists of 258 pairs of dipole-type antennas whose outputs a…
The First Station of the Long Wavelength Array
Patricia Henning, Steven W. Ellingson, Gregory B. Taylor +6
The Long Wavelength Array (LWA) will be a new multi-purpose radio telescope operating in the frequency range 10-88 MHz. Upon completion, LWA will consist of 53 phased array "statio…
Sensitivity of Antenna Arrays for Long-Wavelength Radio Astronomy
Steven W. Ellingson
A number of new and planned radio telescopes will consist of large arrays of low-gain antennas operating at frequencies below 300 MHz. In this frequency regime, Galactic noise can…
