ALOS-2 and Sentinel-1, which have highly enhanced capacity compared to previous SAR satellites, were launched in 2014, and their utilization has been widely expanding as data have accumulated for approximately five years. Other long-operating SAR satellites like TerraSAR-X and Cosmo-SkyMed also contribute to expanding the SAR utilization. Now we are facing a new and abundant era of the satellite SAR, along with a worldwide trend to an open and free data policy of satellite data, under the situation of next-generation advanced and/or constellated SAR satellite plans by both public agencies (e.g. ALOS-4 and NISAR) and private sectors. In addition, SAR technologies with other platforms, such as ground-based SAR with high temporal resolution and UAV (Unmanned Aerial Vehicle) SAR with flexible operability, have also been developed and used for various targets. These facts indicate that the SAR utilization has become widespread in both basic researches (e.g., earth science) and diverse applications (e.g., disaster prevention and forest monitoring). In this session, we would like to invite various kinds of research and application results with regard to SAR, sharing our knowledge and having a discussion for the advancement of the SAR utilization.
