Phased-Array Radar Systems Engineering Training

Phased-Array Radar Systems Engineering Training: A phased array is a computer-controlled array of antennas which creates a beam of radio waves which can be electronically steered to point in different directions, without moving the antennas.

In an array antenna, the radio frequency current from the transmitter is fed to the individual antennas with the correct phase relationship so that the radio waves from the separate antennas add together to increase the radiation in a desired direction, while canceling to suppress radiation in undesired directions.

A phased array antenna is composed of lots of radiating elements each with a phase shifter. Beams are formed by shifting the phase of the signal emitted from each radiating element, to provide constructive/destructive interference so as to steer the beams in the desired direction. The signal is amplified by constructive interference in the main direction. The beam sharpness is improved by the destructive interference.

The main beam always points in the direction of the increasing phase shift. If the signal to be radiated is delivered through an electronic phase shifter giving a continuous phase shift, then the beam direction will be electronically adjustable. However, this cannot be extended without limitations. The highest value, which can be achieved for the Field of View (FOV) of a planar phased array antenna is 120° (60° left and 60° right). With the sine theorem the necessary phase moving can be calculated.

Some of the benefits of a phased-array radar system include:

  • High gain width low side lobes
  • Ability to permit the beam to jump from one target to the next in a few microseconds
  • Ability to provide an agile beam under computer control
  • Arbitrary modes of surveillance and tracking
  • Free eligible Dwell Time
  • Multifunction operation by emitting several beams simultaneously
  • Fault of single components reduces the capability and beam sharpness, but the system remains operational

Phased arrays were invented for use in military radar systems to scan the radar beam quickly across the sky to detect planes and missiles. These phased array radar systems are now widely used, and phased arrays are spreading to civilian applications. The phased array principle is also used in acoustics, and phased arrays of acoustic transducers are used in medical ultrasound imaging scanners (phased array ultrasonics), oil and gas prospecting (reflection seismology), and military sonar systems.
