An active electronically scanned array (aesa), is a type of phased array antenna, that is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.
Summary form only given: an x-band optically-steered phased array radar is developed to demonstrate high resolution multi-target detection the beam formin.

Thus, an array can create a tightly focused beam of signal, which can be steered in different directions by staggering the timing of transmissions made at various points across the array a similar principle is used in reverse in an optical phased array receiver, which is the basis for the new camera.
Drawing on phased array concepts that revolutionized radar technology, the short-range, wide field-of-view extremely agile, electronically steered photonic emitter (sweeper) program will develop a compact, agile alternative to mechanical beam-steering.
A passive phased array or passive electronically scanned array (pesa) is a phased array in which the antenna elements are connected to a single transmitter and/or receiver, as shown in the animation at top pesas are the most common type of phased array.
