Calibration challenges for low frequency radio astronomy

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
A major challenge for all high resolution low frequency radio astronomy is measuring and removing the effects of the ionosphere. The isoplanatic patch size for frequencies below a few hundred MHz is generally much smaller than the field of view. In addition, aperture arrays have beams on the sky which vary dramatically with observing geometry.

Low-frequency radio astronomy engineering in Western Australia

2017 IEEE Radio and Antenna Days of the Indian Ocean (RADIO), 2017
I will discuss low-frequency radio astronomy engineering efforts underway in Western Australia. We carry out this work through the International Centre for Radio Astronomy Research (ICRAR)/Curtin University. The frequency range of interest is ∼50 to ∼350 MHz, which is the Low-Frequency Square Kilometre Array (SKA-Low) frequency band.

Orbiting Low Frequency Array for radio astronomy

2011 Aerospace Conference, 2011
Recently new and interesting science drivers have emerged for very low frequency radio astronomy from 0.3 MHz to 30 MHz. However Earth bound radio observations at these wavelengths are severely hampered by ionospheric distortions, man made interference, solar flares and even complete reflection below 10 MHz.

Solar Radio Astronomy at Low Frequencies

Symposium - International Astronomical Union, 2002
This review is concerned to study of sun at frequencies lower than 1.4 GHz. Emphasis is made on results which illustrate the topics in which GMRT could play a major role. Coordinated studies including spectral and imaging radio observations are important for research in solar physics.

Very low frequency radio astronomy

Advances in Space Research, 1996
Abstract Very low frequency (VLF) radio astronomy covers the frequency range below about 30 MHz (or the wavelength range above 10 m). This is the last window of the electromagnetic spectrum never to have been observed with spatial resolution. This is a range over which the Earth's ionosphere transmits either poorly or not at all.

Solar radio astronomy at low frequencies

2008
Powerful radio radiation often originates from the Sun at decametric and kilometric wavelengths. Radiation from the quiet Sun is produced by the thermal mechanism of bremsstrahlung, and radio bursts of several kinds are produced by the non-thermal mechanisms of plasma radiation and, rarely, gyrosynchrotron radiation.

Introduction to Low Frequency Radio Astronomy

2018
Radio astronomy began at low (ν ≪ 300 MHz) frequencies, but until recently has traditionally been dominated by higher frequency work. With the advent of a new generation of low frequency interferometers and the anticipation of the low-frequency component of the Square Kilometre Array (SKA), the field is experiencing a rebirth.

Wideband low frequency antennas for radio astronomy arrays

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
Antennas in the frequency range 10 to 300 MHz are being designed with all-sky coverage, a low response at the horizon to minimize interference from terrestrial sources, negligible ground loss and a good low noise match to the low noise amplifier (LNA).
