Near-earth space is being used more and more. It is used for navigation satellites, communication systems, space observation and military surveillance. Over time society has become considerably dependent on space based systems. If those systems would break down it would have a huge impact on our daily lives.
But space is a hostile place and the artificial satellites placed up there face all kinds of threats. This is why Joachim Ender, professor at the German Frauenhofer Institute for High Frequency Physics and Radar Techniques, pleaded in his keynote speech during the European Microwave Week for more security for our space systems but also against our space systems. To protect ourselves we need space situational awareness. And the most important sensor to give us that is radar.
