Abstract
Six-port-based continuous-wave radar systems have been used for vibration analysis in predictive maintenance and vital sign sensing applications. A core component of these systems are microwave power detectors used for for the down-conversion. This paper investigates a passive Schottky diode detector regarding its noise behavior. Therefore diode noise measurements are presented to estimate the unknown flicker noise parameters. Based on the derived detector noise behavior, the theoretical limit of the precision of the 24GHz continuous-wave radar system is derived and compared to measurements. A measurement precision of 1µm could be achieved at a baseband bandwidth of 100Hz and a target distance of 1m.
