The concept of an electronically scanned antenna is not new. Early uses of this technology started in the 1960s with warning radars, which were used to detect ballistic missile attacks extensively. The U.S. Navy’s SPY-1 Aegis radar is superlatively known for its electronically steered antenna design. It was established during the 1970’s to protect carrier battle teams against saturation attacks by Soviet Union cruise missiles.
In theory, an electronically scanned array commonly means a phased array, i.e. an array of antennas that produce radio wave beams and rays. Electronically, the emitted waves are steered in the desired direction to a specific point without physically moving the antennas. Electronically scanned arrays must be installed properly and arranged precisely to get appropriate results during real time operations. In an array antenna, the transmitter transmits a radio frequency current, which is then fed to each antenna with the correct phase relationship so as to add radio waves to increase radiations in the exact location and direction, and cancel radiations in undesired directions. In the phased array system, current from the transmitter is transmitted to the antennas through electronic devices called phase shifters, which in turn are controlled by a computer system. This computer system can effectively alter the phase electronically and hence, steer the radio wave beams to the desired location.

Electronically scanned arrays were initially used in defense radar systems to scan radar beams and locate and detect planes and missiles in the sky. These systems are still effectively used by the defense industry for detection and location of foreign threats in air, water or land – so corrective action may be taken as soon as possible. Electronically scanned arrays are increasingly used by several country’s defense industries to target their enemies. Additionally, these systems are finding growing applications and uses in the medical industry to detect and locate problems within the human body. The electronically scanned arrays principle is also utilized in acoustic transducers, acoustics in military sonar detection systems and medical ultrasound scanners.
