Using world largest decameter radio telescopes as probe and basis for developing the LOFAR concept

Ziel

An integrated project directed towards thorough progress of astrophysical, methodological, and technical aspects of the low frequency radio astronomy (from 10 to 100 MHz) is proposed. The project is presented as a precursor of one of the most current line of development in modern radio astronomy - namely, the design of new generation, giant radio telescope operating at low frequencies (LOFAR, SKA). The project consists in developing and installing new means and methods, specifics of low frequency (decameter) radio astronomy by using the world largest (European), low frequency radio telescopes UTR-2, URAN1 ... URAN4, SURA, and Nancay Decameter Array. The ground of the project relies on the broad experience (including a large number of experiments at the international level) acquainted in this field by all the participating teams from Ukraine, Russia, France, and Austria. The features of the radio emission from various objects in the Solar System (including radar probing experiments of the Solar Corona), the Galaxy and Metagalaxy will be investigated, with, in this wavelength range, unprecedented sensitivity (< 1 Jy), instantaneous frequency range (> 20MHz), angular (~ 1 arcsec), time (<1 ms), and frequency (<1 KHz) resolutions, and dynamic range (> 70 dB). This will open opportunities for searching for and studying unknown phenomena (especially taking into account those reserved for deep investigations by using LOFAR), as well as for getting a more precise definition of some still open astrophysical problems. The experimental and theoretical tasks, to be executed in the frame of the Project, will contribute to establish the most valuable scientific programs of any future low frequency radio astronomical projects, to demonstrate the feasibility and interest of building giant, new generation radio telescopes, and to delineate a few astrophysical, technical and methodological recommendations for the next LOFAR instrument.
