On November 16, the 3rd Advanced Symposium on Imaging Radar Earth Observation was kicked off in Changsha. More than 400 experts, scholars, graduate students, and business representatives from some 100 foreign and domestic organizations in the field of radar remote sensing attended the symposium.
Speakers at the opening ceremony of the conference included GUO Huadong, Chairman of the conference and Academician of CAS; Professor ZHU Xuehong, Vice President of Central South University (CSU); Research Fellow LI Jiahong, Chief Engineer of the National Remote Sensing Center of China; Academician YU Qifeng, Vice Chairman of the Hunan Association for Science and Technology, and JIN Yongzhang, Deputy Director-General of the Department of Land and Resources of Hunan Province. The opening ceremony was chaired by ZHU Jianjun, Professor of CSU and Chairman of the organizing committee.
GUO Huadong noted that synthetic aperture radar (SAR), one of the core space-based observation technologies, has been developing vigorously in the cross utilization and comprehensive development of many acquisition technologies. SAR is capable of periodically and dynamically monitoring topography, the environment, resources, and disasters on a global scale in order to meet China's strategic needs, including the “One Belt and One Road” Initiative.
ZHU Xuehong expressed warm congratulations on behalf of CSU during the opening of the meeting, believing that more forward-looking suggestions would be made for the support of imaging radar in monitoring global environmental change and Earth's sustainable development through in-depth discussions during the meeting.
LI Jiahong held that China's imaging radar Earth observation technologies have entered a new developmental stage and are gradually reaching an internationally advanced level. He showed appreciation that the Advanced Symposium on Imaging Radar Earth Observation has become a well-known conference, yielding positive results and proposals for the development of China-made radar Earth observation technologies.
YU Qifeng remarked that the meeting would be an opportunity for making progress and developing wisdom in the application of radar Earth observation technologies, and that imaging radar Earth observation will be developed and applied in Hunan Province. This will be completed in the context of realizing new industrialization, agricultural modernization, new urbanization, informatization and internationalization, and building a resource-conserving and environment-friendly society as well as integrating military and civilian development
JIN Yongzhang commented that Hunan has historically given priority to the research and application of new and advanced technologies and has performed a large amount of research specifically in microwave remote sensing and imaging radar. He also noted that relevant Earth observation technologies have supported important work in science and technology, suggesting that there will be more space for application and development in the future.
Academician WU Yirong delivered an invited speech titled “New Developments of Microwave Imaging Technology”. He introduced the status quo and the development of SAR technology by other countries as well as China’s deficiencies and remarkable progress in microwave imaging in recent years. He also called upon scientists and technicians to foster confidence and encourage innovation, and spurred the young to devote themselves to China’s scientific undertakings.
Academician YU Qifeng gave an invited speech titled “Research on the 3-subimage Processing Method of InSAR and the Application of SAR Images in Navigation and Guidance”. He explained that SAR images are not affected by bad weather such as fog, clouds, or rain, and that SAR can be used for military target identification, SAR image navigation, and precision missile guidance. He also showcased achievements in these fields.
ZHANG Qingjun, Chief Commander and Chief Designer of the GF-3 satellite and Research Fellow of the Engineering Department of the China Academy of Space Technology (CAST), delivered an invited speech titled “Technical Features and Technological Progress of China’s First Multi-polarization SAR Satellite”. He detailed the development of GF-3, China's first high-resolution SAR satellite, from the feasibility demonstration of the system to its launch in August 2016, and then to its on-orbit testing at the current stage. GF-3 has proven to be a major achievement amongst China's high-resolution SAR satellites.
Sigurjón Jónsson, Professor of King Abdullah University of Science and Technology (KAUST) of Saudi Arabia, presented an invited speech titled “Rifting events studied using InSAR on the application of SAR in monitoring crustal movement”, which showcased the advantages of InSAR technologies in monitoring geological disasters such as volcanic eruptions caused by plate movement.
The symposium lasted three days, focusing on the system, imaging, calibration and classification of SAR, as well as the application of SAR/InSAR in mapping and charting, target detection and target identification, glacier and permafrost remote sensing, ocean remote sensing, infrastructure monitoring, urban subsidence monitoring, mining area monitoring, seismic parameter inversion, and agriculture and forestry. It was hosted by the Chinese National Committee of ISDE (CNISDE), co-undertaken by CSU, RADI, the Department of Land and Resources of Hunan Province and Microwave Remote Sensing Committee under CNISDE, and co-organized by the National Remote Sensing Center of China, the Chinese Academy of Surveying and Mapping, the Institute of Geodesy and Geophysics under CAS, Wuhan University, the Chinese University of Hong Kong, Hong Kong Polytechnic University, Beijing University of Aeronautics and Astronautics, Tongji University, China University of Geosciences, and the Institute of Geology under the China Earthquake Administration.
