IDENTIFICATION OF DENT CORN USING L-BAND SAR: CASE STUDY OF KONSEN, HOKKAIDO, JAPAN

摘要

We report results that identification of dent corn using L-band synthetic aperture radar. We carried out study in Nakashibetsu, Hokkaido, Japan. The study area is one of most popular daily farming area in Japan. However the area is cool in summer season. Therefor it is not suitable for corn growth very much. On the other hand, the corn price in the world remains high level. The daily farmers in Nakashibetsu make effort production of dent corn themselves. Therefor we are studying identification of dent corn and trying grasp of production using L-band SAR. We used Pi-SAR-L2 (L-band Air craft SAR sensor developed by JAXA) data that observed in 2013 and 2014 at Nakashibetsu. The observation carried out same orbit angle ALOS-2. As results, the accuracy of identification marked high precision stably more than 90%. On the other hand results different each appeared by 2-year experiment although there was the polarization that linear relation was seen in about the yield. In this year, we are studying using ALOS-2/PALSAR-2.
