Glad it helped, I just now see you are talking beamforming. Beamforming is achieved using phased arrays. I'm not sure if all beam forming uses phased arrays, but one of the terms is just talking about the wave itself (beamforming), while phased array is talking about how the beamforming is achieved. That being said, I don't want to presuppose that you can't beamform form without phased arrays.
