... a solid state system in which all the antenna elements are connected to a single transmitter/receiver and [that] uses phase shifter modules to selectively delay certain parts of the signal, while allowing others to transmit without delay.  3, fiche 1, Anglais, - passive%20electronically%20scanned%20array

One radar that has gained popularity due to its ability to scan a large field of view is the phased array radar (PAR). [One] traditional PAR [is] known as a passive electronically scanned array (PESA). In the PESA, a single transmitter generates a high-powered signal that is transmitted through individual antenna elements. Each transmit element has an associated computer-controlled phase shifter ... that creates a directional beam by adding a phase shift to the signal from each element. The narrow beam is sequentially steered through the field of view by changing the phase at each element.  4, fiche 1, Anglais, - passive%20electronically%20scanned%20array

Toutes les améliorations citées précédemment sont à mettre à l'actif du balayage électronique. Cette technique ne nécessite pas de modules émetteurs-récepteurs à l'état solide, mais simplement des modules de déphasage. Dans ce cas, le balayage électronique est dit passif.  1, fiche 2, Français, - balayage%20%C3%A9lectronique%20passif
