Status and trends in AESA-based radar

Radar technology, predominantly in the area of defence applications, is in a continuous process of extending its present capabilities. Especially Active Electronically Scanned Array (AESA) radars, with their unprecedented degree of operational flexibility, are currently about to revolutionise the performance of air- and spaceborne, naval and ground radars. The current status of AESA radar and the trends in system and technology advances are discussed. Trends on system level will be the use of MIMO-architectures and shared antenna apertures.
