Abstract

This paper presents a novel noncontact vital sign detection (VSD) system, which integrates an entire radar transceiver along with advanced signal processing algorithms in one compact PXI (Peripheral Component Interconnect eXtensions for Instrumentation) system. Realtime signal processing has been implemented using automatic DC calibration based on compressed sensing algorithm and 'differentiate and cross-multiply' (DACM) demodulation algorithm. Experimental results show that the proposed compact instrument based radar is able to measure respiration motions with simple hardware configuration. This facilitates many proof-of-concept studies for noncontact vital sign detection.
