IWR6843AOP: Increase the range of Vital Sign

Part Number: IWR6843AOP
Other Parts Discussed in Thread: IWR6843

Tool/software:

Hello,
There is a problem that I really want to solve.

Currently I'm testing using 'IWR6843AOP' to detect Vital Sign in humans.
I know that the optimized distance is '1 - 1.5m', as shown in the Vital Signs With People Tracking User Guide.
However, I am facing a situation where I have to get Vital Sign information from a distance of more than 2m.
Using CLI_ParsingCLICcommand, setting the distance from vitalSignsCfg from 2.0 to 2.5 has been completed, but the actual distance from VitalSignsCfg has failed to get VitalSigns information. (CLI_ParsingCLICcommand ("vitalSignsCfg 2.0 2.5 512 5 0.15 0.05 100000 300000\r\n)"); )

Is there a way for me to get VitalSign value from a distance of more than 2m? I would appreciate it if you could tell me how. I need your help.


Also, the page below seems to get quite accurate vital sign values from 2.5m distance, and I'm also wondering how you got them.

  • Hi

    IWR6843 d/vital signs emo also provides a configuration which is valid till 6m. You can find the configuration at the below location

    radar_toolbox_2_20_00_05\source\ti\examples\Medical\Vital_Signs_With_People_Tracking\chirp_configs

    You need not modify anything and directly use the 6m configuration

    Regards
