Phased Array (PA)

Last updated: June 15, 2017

What Does Phased Array (PA) Mean?

A phased array is a type of antenna that is composed of radiating elements with a phase transformer.

Phased arrays are used to provide information to multiple computer systems that are used to monitor the presence of corrosion in a given metal by emitting several beams concurrently. Phased arrays are also used to support corrosion mapping in industrial applications.

Corrosionpedia Explains Phased Array (PA)

Phased arrays were first invented by Karl Ferdinand Braun around the year 1905 to aid long-distance radio communication.

A phase shifter is the component of a phased array that generates beams altering the phase of the signal emitted from each radiating element. This alteration provides interference in a constructive or destructive manner to steer the beams in the desired direction. The generated signals are amplified by constructive interference and reduced by destructive interference.
