WebBeamforming microphone arrays are always circular and come in three main patterns: random, spiral, and ring. (In contrast, NAH microphone arrays are always rectangular.) The ring array performs well when the exact distance to the source is unknown, but it lacks dynamic range. The spiral array gives better results, but you can generally achieve the WebPerangkat ini dapat digunakan sebagai OADM serta untuk kebutuhan sensing dan beamforming antena. ... Apollo Inc : Canada.
