Observation of radio emissions from electron beams using an ice target [PDF]

EPJ Web of Conferences, 2019
To observe high energy cosmogenic neutrinos above 50 PeV, the large neutrino telescope ARA is being built at the South Pole. The ARA telescope detects neutrinos by observing radio signals by the Askaryan effect.

Synthetic aperture radio telescopes [PDF]

IEEE Signal Processing Magazine, 2010
Next-generation radio telescopes will be much larger, more sensitive, have a much larger observation bandwidth, and will be capable of pointing multiple beams simultaneously. Obtaining the sensitivity, resolution, and dynamic range supported by the receivers requires the development of new signal processing techniques for array and atmospheric ...
