mmWave Radar-based Vital Sign Estimation in Cluttered Environment

Abstract

Frequency-modulated continuous wave (FMCW) radar provides range measurement for accurate human positioning, and its phase variation provides information for physiological signal detection. The proposed method is designed to distinguish between human signals and environmental clutter, allowing for the accurate identification and localization of individuals. Moreover, we verify that the precise heart rate can be estimated from the signals of multiple nearby ranges of the target range bin.
