Organizing the International Radar Symposium 2015 (IRS 2015), the German Institute of Navigation (DGON) continues a very successful sequence of Radar Symposia, which started in 1998 in Munich, Germany. This conference will be the final IRS event under the chairmanship of Prof. Rohling which is a very good reason to come to Dresden and submit a scientific paper. Due to the rapid development of technologies, radar technique is still an expanding technical and economical segment with practical applications both in civil and military area. The worldwide family of radar researchers, engineers and experts is quite small and everyone from the international radar family is cordially invited to attend the International Radar Symposium 2015 in Dresden, Germany.
