An active electronically scanned array (AESA) is a sophisticated antenna system known as a phased array. It utilises computer control to adjust the direction of its radio wave beam without physically repositioning the antenna and is commonly used in aerial platforms. Launched in July 2021, with funding from the European Commission under the Preparatory Action for Defence Research (PADR), the project European active electronically scanned array with Combined Radar, Electronic Warfare and Communications functions for military applications (CROWN) focuses on the innovative concept of a multifunctional radio frequency (RF) system, which aims at substantially enhancing future defence capabilities, with specific focus on AESA for manned and unmanned aerial platforms.
