Hi Vikas We are working on beamforming for the KAT-7 telescope here at SKA-SA.
The beamformer functionality will be in the same FPGAs as the X-engines in our packetised correlator. The operation will be similar to delay compensation/fringe tracking and the results from the different antennas will be added together to form the beam. Multiple simultaneous beams can be created and the results integrated or dumped out directly via 10Ge. We should have this working in the next few months, there is still a lot of development and testing required. I can send you more info if required. There was a poster up showing the design of a 'pocket' beamformer developed at the GMRT, you might also want to contact them.
