The geometric modulation of synthetic aperture radar (SAR) imagery such as radar shadow, foreshortening, and layover often complicates image interpretation while it contains useful information about targets. Recently, some methods for automatic build

Various polarimetric decomposition techniques have been proposed and demonstrated for more than 20 years. However, they still have never been operational applications because of insufficient validations. The true composition ratio of scattering mecha

The east coast of Japan was heavily damaged in a wide area by the tsunami after the eastern Japan great earthquake on March 11, 2011. NICT conducted observations of the damaged areas by an airborne X-band SAR system (Pi-SAR2: polarimetric and interfe

This paper reports the preliminary analysis of the repeat track interferometry by Pi-SAR2 with RF-NAVI. First, the relationship between the correlation coefficient and the observation conditions such as the baseline length and the antenna look direct

SAR remote sensing has been expected as an efficient rice crop monitoring tool due to its flexible operability with wide swath. Though many researchers have intensively analysed the backscatter, there still exist non-negligible mysteries to extract p

An X-band airborne SAR, Pi-SAR2, has been developed by NICT. It can make polarimetric and interferometric observation with very high spatial resolution of 0.3m. Since 2013, NICT has carried out collaborating observations on research proposals selecte

This paper addresses the evaluation of the digital elevation model (DEM) generated by single pass SAR interferometry using an X-band airborne SAR (Pi-SAR2). In this paper we describe the evaluation experiments by using corner reflectors and show the

Many parameters are required for the measurement of the sea surface currents and the sea levels simultaneously by the along-track interferometry SAR (AT-InSAR). To estimate the elevation or the sea levels from the signals observed by the AT-InSAR, th
