Highly compact impulse UWB transmitter for high-resolution movement detection

Abstract

In this paper the hybrid integration of an FCC-compliant fifth-order Gaussian derivative impulse generator IC together with a compact ultra-wideband Vivaldi antenna is presented. The setup results in a compact FCC-compliant impulse UWB transmitter. Measurements of the impulse shape in time and spectral domain are shown. With this transmitter a movement detection and the precise measurement of the movement deviation value by a correlation measurement technique is presented. This shows the ability of the UWB radar system to operate as a movement detection sensor. The measurements include a breath rate measurement of a human being.
