Abstract

In this contribution, a calibration method for millimeter wave FMCW (frequency modulated continuous wave) radar is presented. The proposed technique utilizes the potential of an adjustable ramp duration to extend the validity range of the calibration measurement at a single position and enables the characterization of material samples in varying distances. Exemplary measurement results in the W-band are presented, proving the accuracy of the method.
