Automobile-based SAR/InSAR system for ground experiments

Abstract

An automobile-based synthetic aperture radar (SAR) system named AutoSAR is described. It is an experimental SAR system operating on the ground, which was developed by the Pohang University of Science and Technology, Korea. AutoSAR can also operate as an interferometric SAR (InSAR) when one additional receiving antenna is used. The swath of AutoSAR is less than 1 km, and the azimuthal coverage is limited only by the storage capacity of the system. SAR and InSAR images obtained at a test site near Pohang, Korea, are presented. Being on an automobile, this system can easily obtain SAR data of any target area with a straight road nearby.
