Synthetic Aperture Radar Lab
Research Field
Dr. Nina Lin has almost twenty years of expereinces in the data processing and various applications of synthetic aperture radar (SAR). Her interest focuses on the following topics:
Geodynamics and Natural Hazards: Developing Interferometric Synthetic Aperture Radar (InSAR) time-series analysis and earth science applications, including earthquake studies, landslide detection and monitoring, as well as flood detection.
High-Precision Engineering Applications: Utilizing Tomographic SAR (TomoSAR) for detecting deformations in buildings across large-scale metropolitan areas, as well as non-traditional persistent scatterer interferometric synthetic aperture radar (PS-InSAR) techniques for the monitoring of offshore wind turbine piles.
Environmental Intellegence: Applying Polarimetric SAR (PolSAR) for environmental intelligence, including crop phenology monitoring and forest watch.
IES SARLab specifically focuses on applications of SAR data. The lab was established in 2018, and has graduated 13 members by the end of 2025. There are currently 10 members in the lab, including post-docs, assistants, graduate students and undergrad students.
The main research facilities in the lab are the high performance computing (HPC) in house of IES and the rich sources of SAR data.
