He has authored more than 1,000 papers published in journals and conference proceedings, and 16 books on theoretical wave analysis, synthetic aperture radar (SAR), unmanned aerial vehicles (UAV), microsatellites, and small antennas. His research interests include theoretically scattering microwave analysis and its applications in microwave (radar) remote sensing, especially SAR and subsurface radar (VLF), including InSAR, DInSAR, and PS-InSAR, analysis, and design of antennas for mobile satellite communications and microwave sensors, development of microwave sensors, including SAR for the UAV, aircraft, stratosphere platform, and microsatellite. Prof. Sri Sumantyo is the General Chair of the 7th and 8th Asia-Pacific Conference on Synthetic Aperture Radar (APSAR 2021 and APSAR 2023) at Bali, Indonesia, and has given more than 300 invited talks and lectures related to SAR and its applications. He is the Co-Leader of the Working Group on Remote Sensing Instrumentation and Technologies for Unmanned Aerial Vehicles of IEEE Geoscience and Remote Sensing Society (GRSS) Technical Committee on Instrumentation and Future Technologies (IFT-TC), and Associate Editor of IEEE Geoscience and Remote Sensing Letters (GRSL). Ming Yam Chua, PhD, was born in Malacca, Malaysia, in 1980. He earned his BEng. degree (Hons.) in electronics and MEngSc. and Ph.D. in engineering focusing on radar system design and radar waveform synthesis techniques from Multimedia University, Malaysia, in 2003, 2007, and 2016, respectively. He was with Multimedia University as a Research Associate from 2003 to 2009, Lecturer from 2009 to 2012, Senior Lecturer from 2012 to 2022, and is currently an Assistant Professor at the School of Electrical Engineering and Artificial Intelligence, Xiamen University, Malaysia. Dr. Chua completed his 23 months postdoctoral research fellowship from Nov 2016 to Sep 2017 at the Center for Environmental Remote Sensing, Chiba University, Japan, working on developing Synthetic Aperture Radar systems and conducting flight missions in Japan and Indonesia. Dr. Chua has delivered numerous grants and consultancy projects in developing synthetic aperture radar systems, developing FPGA applications for radar systems, and human sensing techniques. Cahya Edi Santosa, PhD, received a bachelor’s degree in electrical engineering from Gadjah Mada University, Yogyakarta, Indonesia, in 2003, a master’s degree in electrical engineering from the Bandung Institute of Technology, Bandung, Indonesia, in 2013, and a Ph.D. degree in information processing and computer science from Chiba University, Chiba, Japan, in 2019. From 2003 to 2021, he was a Researcher with the National Institute of Aeronautics and Space of Indonesia (LAPAN), Bogor, Indonesia. He was a Research Associate (Postdoctoral Research Fellowship) with the Center of Environmental and Remote Sensing, Chiba University, from 2019 to 2021. Currently, he is a Senior Researcher at the Research Center for Aeronautics Technology, National Research and Innovation Agency BRIN, Jakarta. His primary interest includes analysis of broadband microstrip array antenna, conformal antenna for mobile communication, circularly polarized horn antenna, and research on synthetic aperture radar onboard UAVs, airborne, and satellite.
