FS-5, paper 5: Earth Observation Instruments with E-Scan Antennas State-of-the-Art and Outlook

Spaceborne radars with electronically scanned antennas are in use on European satellites since the launch of Envisat in March 2002. Despite the higher complexity and consequently cost, electronically scanned antennas are more and more attractive for spaceborne radar. The return materialises either in significantly better system performance or in newly gained system feasibility. The paper will discuss firstly state-of-the-art phased array …
