Full polarimetric time domain calibration for UWB Radar systems

In this paper a full polarimetric calibration for Ultra-Wideband Radar systems is presented. The proposed calibration method is completely performed in the time domain. Conducting the UWB Radar calibration in the time domain has several advantages compared to classical frequency domain calibration procedures. First of all, the possibility to perform a lower number of measurements than in the classical frequency domain calibration, and second that it is by far faster. A complete mathematical description by scattering and impulse response matrices is derived. Proper calibration targets and procedures are discussed and evaluated.
