The measurement system has been built with Stepped Frequency Continuous Wave (SFCW) signal for Radar Cross Section (RCS) measurements in free-space at 220～330 GHz. The system consists of vector network analyzer, Millimeter-Wave Converters and target support structure. The measurement techniques which are used in scattering measurements are verified by RCS measurement data. The system measurement accuracy is control within about ±3 dB at –23.6 dBsm.
