We are very happy to announce that our colleague Li Dexin successfully defended his thesis on 27 November 2017 at the National University of Defence Technology (NUDT), School of Electronic Science and Engineering, Changsha, China with great enthusiasm of his reviewers! His thesis entitled "Processing Aspects, Simulation and Analysis of the Impact of the Atmosphere on GEO SAR Observations" had been under supervision of Dr. Marc Rodriguez-Cassola (see pictures, right), here at the Intitute, who also joined him for this defence in China. Congratulations, Li Dexin, from all colleagues here at the Institute!
