IWR6843: How to calibrate the range measurement in High Accuracy Demo

IWR6843: how to offset the error for measurement value in high accuracy demo

Hi community member,

I send a new thread from this thread because the time has passed.

This thread says the method of calibrate the range measurement is implemented at visualizer level.
But I don't think this is the optimal solution method.

Because there is still any problems for the side of mmwave IC and calculation algorithm.
So, We need to know how to offset in the side of IWR6843.

My customer don't know the method and has trouble.
Please let us know!

Best regards.

    Hi Cruijff

    We'll need more information in order to assist you. Is it possible to get the screenshots of the range profile (please use the autoset button to have the entire plot in view)

    One of two things going on here:

    1. There is a peak at the correct range but a larger peak at the erroneous range. Means we can improve performance with a more precise sensor setup.
    2. There is not a peak at the correct range, likely needs some software change.

    Regards,
