IWR1843BOOST: False detection

Hello

If you look at the 3D version of the plot where does that detected object show up?

Thank you,

Vaibhav

Have you tried the "Range Bias and Rx Channel Gain/Phase Measurement and Compensation" section described in the mmWave SDK?

You can find this section on the following page after installing the mmWave SDK: file:///C:/ti/mmwave_sdk_03_05_00_04/packages/ti/demo/xwr68xx/mmw/docs/doxygen/html/index.html

False detected object has coordinate (-0.06, 0.04, -0.004).

Yes, I have. That didn't solved problem.

After:

Before:

What is the compRangeBiasAndRxChanPhase command you have found and what is the new cfg? Because the point is so close to the antenna, I would strongly recommend that you try this process again. Furthermore, please inspect the antenna. Is there any debris or damage? Try cleaning with isopropyl alcohol.

I used this cfg:

I'll try it again.
There is some debris.

Thanks for your reply.
