Australia has just built an SKA, with other half in South Africa

The antennas are linked together via optic fiber, and able to be linked in different combinations

This project is on a huge scale

What size disc's you planning to use

I'll not use disks but dipole sticks.

I'm noob in radio astronomy and want to build radio telescope array on rooftop of dormitory in University.

Since distance is limited, I decided to emplace several dipole antennas considering below links.

The thing is, I don't have enough knowledgement in here so have no ideas about calculating angular resolutions with more than two antennas.
So, It would be very helpful if you give me a expression to calculate such things.

And I think I can emplace about 10 antennas and maximum distance between antenna is about 8 km.
Is it enough to observate in 20~80MHz with enough accuracy? (arcmin~arcsec )
 

Thank you.
