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 result of the height accuracy on DEM by the cross-track interferometric function of Pi-SAR2.
This paper addresses the generation of the digital elevation model (DEM) by radar interferometry using an airborne SAR data observed from different directions. We demonstrate monitoring an active volcano (Mt. Shinmoe, Japan) by radar interferometry of Pi-SAR2. We improved the part of shadow on DEM by using SAR data observed from four different directions. Furthermore we detected the change of ground...
The great east Japan damaged the east coast of Japan severely. NICT conducted urgent observations of the damaged areas by an airborne X-band SAR system (Pi-SAR2: polarimetric and interferometric SAR 2). In this paper we describe the detection of the damaged area by the earthquake and tsunami with polarimetric SAR data of Pi-SAR2. The space resolution of Pi-SAR2 is 0.3 m (slant-range) [1][2]. These...
The National Institute of Information and Communications Technology (NICT) developed an airborne X-band SAR system (Pi-SAR2: polarimetric and interferometric SAR 2) to monitor the earth's environment and disasters [1]. Pi-SAR2 has polarimetric and interferometric functions with high spatial resolution of 0.3m [2]. In this paper we describe the single-pass interferometric function of Pi-SAR2 and show...
In the National Institute of Information and Communications Technology, Japan (NICT), we have developed an advanced X-band airborne synthetic aperture radar (SAR) system, Pi-SAR2, since 2006, to succeed the X-band polarimetirc and interferometric airborne SAR, Pi-SAR. The Pi-SAR2 has a higher spatial resolution of 0.3–0.6 m in the azimuth direction and 0.3–0.5 m in the range direction, as well as...
