Beamforming with GR

I haven’t done beamforming before, would this be possible using the GnuRadio block?

The KrakenSDR block provides the ‘coherentized’ IQ data to the GNU Radio interface. You can then use that to implement whatever application you like in GNU Radio with that.

Thanks. For rx beamforming would it simply be a matter of summing the different received signals, with each individual signal delayed by a constant determined by the antenna spacing?
