Broadband time-domain terahertz radar: Cross section measurement and imaging

Based on a broadband time-domain terahertz radar system, we performed far-field radar cross section measurements of two metal scaled models at terahertz frequencies. The novel broadband radar can provide not only frequency-averaged RCS but also RCS distributions at arbitrary frequency. The measured...

Summary:Based on a broadband time-domain terahertz radar system, we performed far-field radar cross section measurements of two metal scaled models at terahertz frequencies. The novel broadband radar can provide not only frequency-averaged RCS but also RCS distributions at arbitrary frequency. The measured terahertz RCS of the models can be scaled to that of the full-size real object at conventional radar frequencies. In addition, imaging of the scaled models based on filtered back projection algorithm has been proved to be helpful for finding the main scattering points.
