Is it possible to have a network of separate (but co-located) 'receivers' (antenna + adc) act as a phased array receiver?
Supposing one can get very precise timestamping on each receiver, couldn't all the receivers be assembled as a phased array?
I'm thinking about putting a bunch (4 for starters, at least 16 after) of uwb antennas and space them on a panel pointing all in the same direction, then for each antenna having a rtl-sdr or something better if necessary to acquire the signals with a very precise clock.
I want to receive specific signais, timestamp them precisely and then record them. Later in post processing, for some specific timestamp, I need to check the presence of the signals (using the whole array) and perform some analysis on them.
