Phased array - Wikipedia
WEBIn antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions without moving the antennas.
Phased Array Antennas: Principles, Advantages, and Types
WEBA phased array antenna enables beamforming by adjusting the phase difference between the driving signal sent to each emitter in the array. This allows the radiation pattern to be controlled and directed to a target without requiring any physical movement of the antenna.
Phased Array Antenna Patterns—Part 1: Linear Array Beam ... - Analog
WEBThis part 1 of 3 series intends to help engineers, who are working on phased array subsystem or component visualize how its impact on a phased array antenna pattern.
Antenna Arrays (Phased Arrays) - Antenna Theory
WEBAn antenna array (often called a 'phased array') is a set of 2 or more antennas. The signals from the antennas are combined or processed in order to achieve improved performance over that of a single antenna.
Adaptive Antennas and Phased Arrays — Online Course
WEBAdaptive antennas and phased arrays, with rapidly scanned beams or multiple beams, are commonly suggested for radar and communications systems in ground-based, airborne, and spaceborne applications that must function in the presence of jamming and other sources of interference.

Adaptive Antennas and Phased Arrays - MIT OpenCourseWare
WEBPart one (lectures 1 to 7) covers adaptive antennas. Part two (lectures 8 to 16) covers phased arrays. Parts one and two can be studied independently (in either order). The intended audience for this course is primarily practicing engineers and students in …
Antennas - Phased Arrays - Antenna Theory
WEBAntennas - Phased Arrays. If a plane wave is incident upon an antenna array (Figure 1), the phase of the signal at the antennas will be a function of the angle of arrival of the plane wave. If the signals are then added together, they may add constructively or destructively, depending on the phases. Figure 1.
