Accuracy error of the Difference between Real distance and min/max parameters of Vital Sign project

This question start from the following link:

https://e2e.ti.com/support/sensors/f/1023/t/851076?tisearch=e2e-sitesearch&keymatch=Accuracy%252520error%252520of%252520the%252520Difference

I continue question on AWR1642 forum.

Question is how to handle this range accurately shown in the above picture. Can you advise how to do automatic adjustable parameter setting covering 0.2 to 4 meter?

I note that Earlier answer was that Demo is not intended for that range coverage.

How can I make it more accurately and adjust min/max parameters automatically without setting min/max range (we only covers up to 4 meters) ?

Please guide us . Thanks in advance,

Hi Kisub,

This application is limited to fixed range of object to detect the vital sign.

Let me assign to concern person who can provide more inputs here.

Regards,

Jitendra

HI,

If I understand correctly your question is regarding improving the performance of the demo at larger distance. Up to 5m.

In order to do that the gain has to be increased.

Two options are as follows

using a lens to improve the gain by focusing the beams
using beamforming to increase the gain by using multiple TX

thank you
