About the Webinar

LuTan-1 (referred as LT-1) is an innovative spaceborne Earth observation mission containing two satellites, feature each an advanced full polarimetric L-band SAR system. The duration of the mission is divided into two phases. In phase I, two satellites fly in a formation with a variable baseline, and the bistatic InSAR stripmap mode is utilized to acquire the global digital elevation and terrain models with high accuracy and spatial resolution. In phase II, two satellites shall share the common reference orbit with a 180-degree orbital phasing difference. The revisit time will be decreased to 4 days and topographic variations with millimetre accuracy at large scale can be measured using the differential InSAR technique.  Beyond these objectives, many promising observation products will be acquired, e.g. the single-pass polarimetric InSAR for forestry application, the hybrid polarimetric for land classification, etc. LT-1 will improve the capacity of current SAR system for acquiring multi-dimensional information of Earth dynamic processes and monitoring the global environment. Currently, the twin satellites are being assembled and tested, and it is scheduled for liftoff in the Winter of 2021.

Speakers’ Bio

Prof. Dr. Wang received the B.S. degree in Communication and Information System from Henan University, Kaifeng, China, in 2002, the Ph.D. degree from Graduate University, Chinese Academy of Sciences, Beijing, China, in 2007.

Since 2012, Dr. Wang is Co-Principal Investigator (PI) for Helmholtz-CAS Joint Research Group concerning Space-borne Microwave Remote Sensing for Prevention and Forensic Analysis of Natural Hazards and Extreme Events. Currently, Dr. Wang is responsible for several National high-resolution spaceborne imaging radar missions. His major focus is PI for the SAR payload of LT-1, which is the first spaceborne mission in “National Civil Space Infrastructure (2015-2025)” in China. He in charge of overall performance of LT-1 SAR system, covering the scientific (bistatic SAR spectrum and processing algorithms), conceptual (spaceborne bistatic SAR system design and conception), and engineering (synchronization and system validation) aspects.

Prof. Dr. Wang is a Senior Member of the IEEE.
