| Outline of Final Research Achievements |
This report discusses a polarimetric data analysis for agricultural monitoring by using multi-temporal L-band spaceborne polarimetric synthetic aperture radar data. On May 24, 2014, Advanced Land Observing Satellite 2 (ALOS2) was launched. ALOS2 is the follow-on satellite of ALOS and has the Phased Array type L-band Synthetic Aperture Radar 2 (PALSAR2). PALSAR2 provides an image with a higher resolution (maximum: 6m) in polarimetric mode as compared with the image of former L-band SAR (PALSAR) and its revisit time is 14days. Then, it is expected that PALSAR2 is used for agricultural monitoring. In order to do it, we determined a test site was a reclaimed land in Isahaya bay where there is large cultivated land and have examined the field survey and polarimetric data analysis. In this report, we used two polarimetric PALSAR2 data which were acquired in August and September, 2015 and analyzed them by two decomposition techniques. The good results were obtained.
