In case you were interested in the frequencies they were sweeping though:
We reproduced a state-of-the-art FMCW radio designed
by past work on wireless vital sign monitoring [7]. The
device generates a signal that sweeps from 5.46 GHz to
7.25 GHz every 4 milliseconds, transmitting sub-mW power.
The parameters were chosen as in [7] such that the transmis-
sion system is compliant with FCC regulations for consumer
electronics
I wonder if you can use lower frequencies? Since we are surrounded by radio waves maybe you can use use on those cheap SDRs and look for the 50-150hz space to see if you can pick up heart rate.
