Abstract

This paper presents a noise tolerable method for FMCW radar systems to detect vital sign under strong reflected interference signals of stationary clutter. By using phase accumulated demodulation, vital sign detection can be demodulated clearly even under existence of strong clutters influence, and noise can be decreased so that the delay-line can be reduced for the compact system implementation. From the measurement results, the measured absolute range has 4.69% error from 0.5 m to 3.05 m in average. Moreover, the vital sign is 2.25% and 1.49% error with stationary clutter interferer 0.75 m and 1.3 m behind the human target respectively.
