Interferometric synthetic aperture radar (InSAR) and its applications to study volcanoes(part 1: Principles of InSAR)

Zhong Lu, Jixian Zhang, Yonghong Zhang

Abstract

Interferometric synthetic aperture radar (InSAR) is a remote sensing technique capable of measuring ground surface deformation with subcentimeter precision and spatial resolution in tensofmeters over a large region. This paper reviews the basics of InSAR technique, illustrates how InSAR works, and discusses issues related to InSAR deformation mapping.
