Low frequency VLBI research for solar studies and as a prrsor to Space VLBI with RadioAstron

Objective



It is proposed to join the scientific and technical potentials of research groups from Switzerland, Italy, Russia, Ukraine, India, USA and Sweden for equipping the radio telescopes of the former Soviet Union by standard receiving-recording hardware in the 327 MHz band in order to conduct a multifaceted research programme in interests of future Space VLBI RadioAstron mission and solar studies together with telescopes Noto, Ooty, GMRT, Shanghai, Urumqi using the technique of Very Long Baseline Interferometry (VLBI).
The high sensitivity of this VLBI array in combination with base lengths of different lengts and directions will allow to receive new scientific data on he physics and the turbulence of the interstellar and interplanetary medium, the spatially-temporal structure of non- stationary solar radio sources, the appearance of solar coronal irregularities.
This also will be a first step of the creation of a Ground Telescopes Network for future joint observations with a space VLBI mission. A list of sources for space VLBI will be prepared. The recommendations for the operation of RadioAstron will be made on the basis of scattering effect investigations.
