Abstract
Heartbeats can be measured at a distance using radar to record the chest movements. The physiological motion appear as modulations in both phase and amplitude in the radar recording. In this paper, a single reflector model of the heartbeat is used to estimate the chest motion and find the movement in millimeters. Experimental results from 10-18GHz measurements are presented, and the validity of the estimation discussed.
