AWR1843BOOST: How to understand Beam Steering Example GUI output

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Hello

I am trying to run MRR Beam Steering example on AWR1843 with indoor environment. Actually I don't understand the output of mRR_Viz_1_4.exe enough. My GUI option is:
Max velocity= 10,
Max range width= 40,
Max range depth= 40,
Max height= 30.
My test was depending on a human, moving in front of the radar in different directions but the result in GUI in not reasonable, how to understand and test the output of the figure in Beam Steering example?

Also what's the resolution of angle and distance in AWR1843? Is the object data coming from awr1843 preconfigured with angle resolution and distance resolution?

Thanks

    Hi,

    It is helpful to understand that the matlab visualizer configuration parameters only configure the matlab GUI. They don't have any effect on the target code configuration

    For your evaluation I recommend you start with the following lab: "labs\lab0007_medium_range_radar"

    The reason for this is that USRR (MIMO) mode is not functional in the "labs\lab0011_mrr_beamsteering".

    This may be something you want to evaluate as well.

    First start your evaluation with a Corner Reflector.

    Angular resolution is 2x better for USRR mode than for MRR mode.

    Please use google site search to find more information about angular resolution

    "site e2e.ti.com angular resolution"

    Thank you

    Hi Cesar

    Sorry of late reply.
    I tested lab0007_medium_range_radar and lab0011_mrr_beamsteering on AWR1843 and found that result. If person moves in front of the radar sensor it will track the person, but I don't find the difference, Is Beam Steering just has better result?
    Thanks you

    Hi,
     
    Beam steering will have better results if you orient the beam at an angle larger than about 30deg.
     
    If the beam is sweeping different angle (as it is configured out of the box) , you will probably not see a difference
     
    Thank you
