Abstract

the unknown-thru calibration technique is being used to achieve a system level calibration at milli-meter frequencies (>50 GHz) on the robotic ranges at NIST. Since this requires the use of a full bi-directional measurement, which takes longer than traditional single direction antenna measurements, we explored the value of the additional data acquired. We found that we can use it to verify antenna/scan alignment, image the scattering from the positioner/facility, and look at system due to LO cable flexure.
