Calibration of Pi-SAR2 Polarimetric Observation Data Using ABCI

The polarimetric observation data of Pi-SAR2, an airborne polarimetric synthetic aperture radar, are very valuable because of its high resolution, but it cannot be used effectively because the data are not well calibrated with respect to elevation. Therefore, we have calibrated the data according to the observation conditions. The Pi-SAR2 observation data are very large due to its high resolution and require sufficient computational resources to be calibrated. We utilized the AI Bridging Cloud Infrastructure (ABCI) to calculate them. This paper reports on the calibration and scattering power decomposition of the Pi-SAR2 observation data using the ABCI.
