IWR1843: can iwr1843 measure heartbeat and respiration from 3m to 6m without contact

Hello,

Please see the following demonstration of heartbeat and breath rate measurement with the IWR6843. Measurements with the IWR1843 would be very similar. The existing algorithm is only configured to measure vital signs at short ranges, but it can be modified to measure at longer ranges. 6m might be difficult to get good enough signal integrity for the heart rate, but it is possible.

Is there a reason you want to use the IWR1843 in the 77GHz spectrum for measuring heart rate. Most applications we see require a 60GHz solution like the IWR6843.
