for something?

It might be a good idea to check what the radio astronomers have done
during the last decades and hopefully some good ideas could be found
that could now be implemented using low cost generally available
hardware and software (which is an absolute requirement for any
coordinated effort between several hams :-).

Looking at submarine sonar techniques and producing an analogue for radio would
also be very useful. Beam steering from an array of broad beam width transducers
and digging into the noise are both commonly done.
