THz time domain monostatic radar cross section measurement of metallic plates and dihedrons

THz Radar Cross Section(RCS) measurement setup based on THz Time Domain Spectroscopy (TDS) is built to provide large scaled targets test ability in recent years. As calibrations, the metal plates and dihedrons are used in our experiments. The measurements are performed in a monostatic terahertz time-domain setup. The author proposed time domain and frequency domain calibration methods for angular RCS of calibrations, comparing the measurements with the theory to verify the ability of the time domain measurement setup.
