Orderer
  • Sejong University
Dev’t Overview
  • Establishment of a remote monitoring technology by detection of surface displacement of a volcano
Operation Concept
  • Development of a semi-automatic earth surface displacement mapping system by use of atmospheric phase
      measurement algorithms
  • Development of a quarterly time-series earth surface displacement measurement system suitable for
      the Mt. Baekdu volcano
  • Development of a precision earth surface displacement display system for monitoring of volcanic activities
System Composition
  • Development of an algorithm on surface displacement caused by volcanic activities by use of
      SAR satellite data
  • Development of time-series analysis algorithms proper for the characteristics of the changes in atmosphere
      and surface properties
