AWR1843AOPEVM: Cloud points explanation for detected objects

Part Number: AWR1843AOPEVM


Hello,

I have a question regarding the representation of the cloud points while using the visualizers provided as demos. I have the issue that for example a pole is represented with couple of points only in it's upper area. My expectation was that a pole will be represented with cloud points along it's vertical axis.

When i checked document TIDUEZ2 – MARCH 2021 - i get the feeling that it was the same for you testing as well.

For example for the wood post the cloud point representation consists of a cyan blue color with would mean a height of -0.2 to -0.4 m.

So my questions would be:

It there a way to use the visualizer so you can get a  more accurate cloud point representation of real objects?

What it's the limiting factor to be able to have such a representation?

Thank you,

Valentin

  • Hi

    Your observation is correct.

    The reason why one gets only one detected point in this environment (static detection, pole) is the RCS of the object. This results in an SNR that is low.

    The SNR can be improved by increasing the number of chirps. For some objects this will result in more reflections. For some other objects this will not be sufficient to increase the number of detected points.

    Thank you
