In this paper we present the first high resolution SAR measurements performed in the lower terahertz region with the MIRANDA-300 system. The millimeter wave FMCW radar is operated at 300 GHz and provides a bandwidth of more than 40 GHz leading to a range resolution of a few millimeters. With an output power of around 5 mW over the complete bandwidth the system is mainly designed for short range applications up to several hundreds of meters. The capability of the radar has also been investigated in ISAR measurements. The presented results demonstrate the high image quality and the richness of details.
