How Does a Radio Interferometer Work?

-- Vic | June 23, 2025

Question:

How are the measurements from the VLA processed? Is there a simple block diagram of the process that you could provide? Are the dishes in the array paired 2 at a time or paired with all the dishes in the array? How long is the integration interval? How many samples per interval?
