From a City to a Country: Multi-scale SAR Processing Techniques and Applications

2. Performance Study of Landslide Detection Using Multi-Temporal SAR Images

1. Natural Hazard Monitoring with InSAR
My team implements multiple InSAR processing flows on the High Performance Computing (HPC) environment within the Institute of Earth Sciences, Academia Sinica. The processing flows established include small baseline subsets approach, persistent scatterer approach and phase linking approach. We use these methods to monitor different types of natural hazards in Taiwan and in Southeast Asia. We also open up the HPC to students and collaborators from various universities/institutes.

2. SAR-based Change Detection
We develop the Growing Split-Based Approach (GSBA) algorithm for automatic change detection based on multi-temporal Synthetic Aperture Radar (SAR) imagery. The detection kernel is the Bayesian probability generalized to a three-class problem rather than the conventional two-class problem. GSBA is statistically robust and computationally efficient, with a user-friendly driver file for operational applications. It can also be utilized for other scenarios, such as changes associated with landslides.

3. Mobile Shales in Active Orogeny
There are many active mud volcanoes onshore and offshore southwestern Taiwan, yet the source area at depth is usually not clearly imaged. We utilize the industry-level seismic processing software, Geovation, to reprocess long-offset seismic data in order to figure out the geometry and physical properties associated with the patches of mobile shales at depth. The goal is to unravel the role mobile shales play in an active orogenic belt.
