Phased arrays

Interruption of plant operation can be avoided if non destructive testing inspections are performed on-line at operating temperatures, which may be up to several hundred degrees Celsius in a petrochemical or electric power generating plant. However, there are operational tempera…

A new method for null steering in phased arrays by controlling the element positions is presented. This technique is studied both theoretically and experimentally for placing nulls in the radiation pattern to suppress interference and unwanted signals. The study shows the effect…

Phased arrays have many applications such as Radar Communication, Satellite Communication, and Wireless Local Area Networks (WLAN). For the traditional phased array, a phase shifter is used with each antenna element to establish a constant phase progression along the antenna arr…
