Abstract:
We are investigating the possibility to construct a radio observatory for cosmic sources: high energy particles and extragalactic radio sources.
The ultra high energy cosmic particles play an important role in the Big Bang scenario, quantum gravitation etc. and also represent a key to unveil the mystery of the cosmic accelerators. Thus their detection is scientifically important. On the other hand, radio observations of cosmic sources represent a reliable tool for advances in astronomy.
The first step for a radio observatory formed by phased array of antennas would be to determine its optimal geometry. Second, the types of antennas together with their characteristic parameters should be determined. The main performances of the observatory (spatial resolution, sensitivity, energy threshold etc.) are also discussed.
