Ryo Natsuaki, Department of Electrical Engineering and Information Systems(EEIS), wins The 21st Remote Sensing Symposium, Young Researcher Award , SICE Technical Committee on Remote Sensing

The 21st Remote sensing Forum was held on February 27, 2014 sponsored by SICE (The Society of Instrument and Control Engineers), RSSJ (The Remote Sensing Society of Japan) and IEEE GRSS (Geoscience and Remote Sensing) Japan Chapter. The paper title is Ryo Natsuaki and Akira Hirose "Improvement of SAR interferogram accuracy in mountainous regions using local co-registration method."

<About awarded research>

Interferometric Synthetic Aperture Radar (InSAR) is widely investigated to observe landscape and its deformation. However, there are massive rotational points named singular points (SPs) in the interferogram. They are attributed to, for example, slight difference of incidence angle and water vapor inhomogeneity. We proposed a sub-pixel co-registration method employing the SP number as the evaluation criterion in parallel to the assistance of the amplitude-implied phase gradient and the low-pass filtered reference interferogram. Experimental results showed that the proposed method is effective in the mountainous region, which is generally hard to observe the landscape.
