Abstract

This paper addresses the generation of the digital elevation model (DEM) by radar interferometry using an airborne SAR data observed from different directions. We demonstrate monitoring an active volcano (Mt. Shinmoe, Japan) by radar interferometry of Pi-SAR2. We improved the part of shadow on DEM by using SAR data observed from four different directions. Furthermore we detected the change of ground height inside crater by comparing the data on February and October in 2011.
