You can find the basics of Gregorian antennas in the attached document (Multiple Reflector Antennas).
After you know the basics, you can use ICARA software to analyse the performance of the different feeds.

not exactly cassegrain but similar to that differing in real or virtual focus
 

Thanks Tsvetelin,
I did some reflectors design some time ago, and this document was very helpful.
 

I also had problem installing it, may you verify it please?
