SAR investigation over the Baegdu stratovolcanic mountain: Preliminary results

Mt. Baegdu, a Cenozoic stratovolcano, are studied using SAR and JERS-1 OPS data. We use ERS-2 SAR and JERS-1 SAR to generate interferograms and coherence maps. One of JERS-1 SAR pair acquired with 1100 days interval produces a relatively excellent interferogram. Although there is a height still trend to be removed, preliminary DEMs are successfully estimated from two JERS-1 interferograms over the study area. Because ERS-2 interferogram have a good coherence around the top of Mt. Baegdu and volcanic plateau western part in the study area, it was only possible to obtain DEM in those area. These results are to be utilized in selecting GPS station and monitoring surface change over the region. We will apply DInSAR technique with support of GPS and micro-seismic data in future study.
