hi, first of all, thanks about your help for my first question here. I'd need something else... I have to develop an effective algorithm for beamforming as a part of my desing. I'm looking for information about the diferent existing possibilities but I'm not finding good articles and documents that explain these algorithms clearly. Could someone tell me where looking for? Thanks!

Then it's just a matter of adding things in phase according to the direction you want. Now, DOA is another matter altogether. That's generally based on a relative phase measurement. So, likely you need to form 2 or more beams for that purpose. Fred

Transient or Stationary? Interference or not? And so on... Rune
