transducer or replacing the acoustic lens. Phased arrays comprise multiple transducers, which are electronically delayed to build a constructive interference wavefront. By changing the time delays between the elements of the array, the resulting wavefront can be pointed to different directions (beam ...
The signals transmitted from different antennas are converted intoelectromagnetic wavesthat combine in the air. Considering a receiver located at some distance right in front of the transmitting antenna array, thepropagation pathlengths from the different antennas to the receiver are essentially the same...
