Quadrature Receiver Benefits in CW Doppler Radar Sensors for Vibrations Detection
Techniques for contactless detection of vibrations claim a wide range of applications in both civil as well as biomedical contexts. In this work, two Doppler radar signal processing solutions, respectively based on single-channel and quadrature receivers, are implemented and compared as alternative to standard sensors for contactless identification of vibrations. The detection ability at different target ranges is tested through numerical simulations.
