An UAV SAR Footprint Generator using GPS-Aided INS

摘要

The Synthetic Aperture Radar (SAR) is a type of radar system that utilized relative motion, from the antenna to the target region, to compute the large number of frequency-modulated echoes for image formation. On the other hand, the Global Positioning System (GPS) integrated with the Inertial Navigation System (INS) had been applied in various motion sensing applications. In this paper, a developed GPS-aided INS is mounted on ah UAV for motion sensing in SAR mission for motion sensing and SAR footprint generation. A software is written to provide the UAV SAR footprint modeling outputs from the motion data.
