KIGAM and KNU are developing a ground-based Arc-scanning SAR system (ArcSAR) mounted on a truck. The system achieves the coherent integration of radar returns from ground targets by the circular motion of the antennae attached to the end of an extendable arm. Precise control of antenna position and the extended coherent-integration-length enable the(More)
microwave frequencies as airborne and spaceborne SAR systems. GB-SAR system has real time capability and flexibility for monitoring in emergency cases such as sudden landslide better than satellite SAR system. Many research papers have been presented using GB-SAR interferometry techniques. These studies are concentrated to a monitoring of natural hazards,(More)
We made a ground-based synthetic aperture radar (GB-SAR) system and tested its interferometric SAR (InSAR) measurement on the displacement of a trihedral corner reflector with atmospheric correction in terms of humidity and range. The GB-SAR worked at C-band with the synthetic aperture length of 5 m. Fully-polarimetric images were obtained with resolutions(More)
—This paper presents the development of a ground-based arc-scanning synthetic aperture radar (ArcSAR) system mounted on a truck. ArcSAR formulates synthetic aperture by a horizontal circular motion of antennas attached at the end of an extendable boom. The ArcSAR system is designed to operate in two different imaging modes: the spot mode and the scan mode.(More)
—This paper presents the variation of the radar backscattering of intertidal mudflats in the west coast of Korea observed by Radarsat-1 synthetic aperture radar (SAR) images and investigates the related factors by an indoor experiment and a field experiment using a ground-based C-band scatterometer. The 15 Radarsat-1 SAR images of the intertidal mudflat(More)
The Korea Institute of Geoscience and Mineral Resources (KIGAM) and Kangwon National University (KNU) GB-SAR team have been developed a fully polarimetric and interferometric GB-SAR system over past several years. The main objective of this study is to analyse a polarimetric characteristics of various terrain targets measured by a polarimetric GB-SAR system(More)
Ground-Based SAR system that obtains a high resolution 2D image on the ground is a new type of SAR system such as airborne and space-borne SAR. The measured fully polarimetric SAR images with HH, HV, VH, and VV were focused using the Deramp-FFT (DF) algorithm in terms of their image formation principles. SAR polarimetry technique is concerned with control(More)
