For almost a century, work has been proceeding to continuously improve radio detection and ranging (radar) systems. The development of frequency-modulated continuous-wave radar (FMCW) systems and the application of millimeter waves, have allowed radar systems to measure vital signs. No experimental work has been performed to test whether FMCW radar systems are able to measure displacements on the order of vital signs when multiple moving targets are in the path of the beam. This paper presents the construction and analysis of an FMCW radar system operating at a central frequency of 96 GHz being linearly modulated at 10 kHz over a bandwidth of amplitude 96 MHz, culminating in the measurement of two targets moving with displacements similar to vital sign signatures.
