Electronic and optical methods of shaping wall antenna direction-finding characteristics have been presented. Advantages and disadvantages of each method have been described, with particular attention paid to weight systems being of key significance for beam forming process. It has been proved that in case of digital beam forming, the calculated weight values must be approximated following the spit of the applied phase shifters and mufflers. The authors conclude that the method selection depends upon antenna array components number (beam width). It is preferred to apply optical method for very narrow antenna beams.
