Professor Seong-Ook Park, He received the B.S. degree from KyungPook National University, KyungPook, Korea, in 1987, and the M.S. degree from Korea Advanced Institute of Science and Technology (KAIST), Daejeon, in 1989, and the Ph.D. degree from Arizona State University, Tempe, in 1997. From March 1989 to August 1993, he was a Research Engineer with Korea Telecom, Daejeon, working with microwave systems and networks. He later joined the Telecommunication Research Center, Arizona State University, until September 1997. He is a member of Phi Kappa Phi Scholastic Honor Societies. He has been a member of the faculty at the Information and Communications University from October 1997 to 2008. Since 2009, he has been a full professor at KAIST. He has over 200 publications in refereed journals.
He had served as the Director General, Satellite Technology Research Center at KAIST from 2016 to 2018, where he has been involved in the development of two small satellites as NEXTSAT-1 (Mission called NISS: Near-infra red Imaging Spectrometer for Star formation history) and NEXTSat-2 (Mission: Synthetic Aperture Radar).
He also served as President of The Korean Institute of Electromagnetic Engineering and Science (KIEES) in 2022. Currently, he is serving as the chair of South Korea National Committee of URSI since 2024.
His research interests are in the area of antenna system, bird and drone detection radar system, and Synthetic Aperture Radar.
Abstract
Small satellites can provide the wide range of mission including space exploration, science, and earth observation. This talk focuses on current antenna system technologies of small satellites in communication, earth observation, and scientific missions, followed by a deep dive into antenna system development from parabolic reflectors to modern phased arrays.
Small satellite with the synthetic aperture radar (SAR) will be introduced. In addition, the technological advances and available mission scope in SAR small satellites are described. The presentation addresses critical engineering challenges in antenna integration, including size-weight-power constraints, mechanical deployment, and future antenna technologies which might address mission requirements.
The talk concludes by emphasizing that antenna systems are no longer peripheral components, but core drivers of innovation and performance in modern satellite missions.
