Abstract

GB-SAR (Ground-Based Synthetic Aperture Radar) system is an imaging radar that obtains high resolution 2-D image through a synthetic aperture effect from the accurate linear-motion control of antenna on the ground. The highly versatile system configurations and accurate repeatability of GB-SAR operation allow one to accurately monitor the stability of surface scatterers with millimeter accuracy by SAR interferometry. In this paper we introduce the development of a GB-SAR system and show the possibilities of SAR polarimetry and interferometry such as DInSAR, Cross-Track InSAR, Delta-f InSAR, and PSInSAR.

GB-SAR (Ground-Based Synthetic Aperture Radar) 시스템은 지상에서 안테나의 정밀한 일축 제어를 통해 합성 구경(synthetic aperture) 효과를 얻어 높은 해상도의 2차원적 영상을 얻는 영상레이더(imaging radar)이다. GB-SAR 시스템의 높은 유연성과 안정된 반복 측정으로 SAR 간섭기법을 통하여 산란체의 시간에 따른 변위를 mm 정밀도로 모니터링 할 수 있다. 이 논문에서는 GB-SAR 시스템의 개발을 소개하고 여러 가지 영상 획득 모드를 통하여 얻어진 다편파 SAR 영상을 비롯하여 DInSAR, Cross-Track InSAR, Delta-f InSAR, PSInSAR 등 GB-SAR 시스템을 이용한 다양한 간섭기법의 응용 가능성을 보였다.
