I am now more than 40 years working on Radar. I was the first Satellite SAR Designer in Europe. I was responsible for the Radars on ERS-1, X-SAR/SIR-C and SAR Lupe (German Radar Reconnaissance Satellite). I founded RST Radar Systemtechnik GmbH and AG in 1992. Since 2008 I am Honorary Professor at University of Stuttgart. I give trainings and lectures on Satellite SAR to companies and organizations in Sweden, Canada, South Korea, Singapore and China and lectures on GPR to organizations and companies in Australia.
