AWR1843BOOST: How to measure reflected signal's strength and phases continuously - 30 to 50 packets

Part Number: AWR1843BOOST

Dear

When I print reflection coefficient in AWR1843EVM, sometimes reflection coefficient shows very big numbers(Distance 1 cm).

If I want to measure 30 to 50 packets continuously with this EVM, how can I set it up? In the continuous mode, it seems to support only 4 subframes.

Also, I would like to plot phase of received signal.

Please guide me and elaborate it with example code as much as you can how to approach to measure packets continuously within very short distance such as 1 cm.

Thanks for your fast response in advance,

BR,

Hi,

Are you placing any reflector in front of the sensor at 1cm?

At this short distance you may have to reduce the tx power.

What is the sw used for these experiments?

Thank you

Cesar

It is a type of SW instrument to analyze materials such as pure water, gelly, hard cover.

then how can I reduce TX power?

Hi Kisub,

Please see the mmWave SDK User Guide on Page 20.

Let me know if you have more questions.

Cheers,
