MASER: a toolbox for low frequency radio astronomy

2018
The MASER (Measuring, Analysing and Simulating Radio Emissions) project provides a comprehensive infrastructure dedicated to low frequency radio emissions (typically < 50 to 100 MHz). The four main radio sources observed in this frequency are the Earth, the Sun, Jupiter and Saturn. They are observed either from ground (down to 10 MHz) or from space.

Low-frequency radio astronomy and the origin of cosmic rays

2000
One of the longest standing mysteries in physics and astronomy is the origin of cosmic rays. Space-based low-frequency radio astronomy holds the promise of providing answers to key pieces of this important puzzle. There are a number of important reasons why the study of Galactic low frequency emission will offer new insights into this 87 year-old ...

Very low frequency radio astronomy from the moon

2008
Lunar development is virtually certain to occur in the next 10–20 years. Very low frequency radio astronomy observations can and should begin with the first lander. A modest yet powerful near-side array should be built if backside development will be substantially delayed. A major backside array should be constructed when technology and funding permit.

Algorithms for Categoric Analysis of Interference in Low Frequency Radio Astronomy

Journal of Electromagnetic Waves and Applications, 2007
A study of the various types of terrestrial electromagnetic interferences categorized in terms of frequency, flux density, radio-direction, and statistics on a regular basis is essential at the radio telescope sites for understanding the radio environment viz.

A satellite-borne receiver for low-frequency radio astronomy

Radio and Electronic Engineer, 1968
A receiver designed to measure the galactic noise spectrum in the range from 2 to 4.5 MHz and flown in the Ariel III satellite is described. Problems arising from the use of a loop antenna with a swept receiver and the exclusion of spurious signals from terrestrial sources and other experiments in the payload are discussed. Preliminary results indicate

An evolutionary sequence of low frequency radio astronomy missions

2008
A progression from simple, near-term experiments to Explorer-class dedicated missions to a large lunar faxside array is a natural way to develop the observational capabilities needed for radio astronomy at low frequencies. This continuous increase in mission capabilities and scientific return is similar to the progression of infrared and X-ray missions.

The current status of low frequency radio astronomy from space

2000
Ground-based radio astronomy is severely limited by the Earth's ionosphere. Below 15 - 20 MHz, space-based radio observations are superior or even mandatory. Three different areas of astronomical research manifest themselves at low radio frequencies: solar, planetary, and galactic-extragalactic.
