AWRL6844: The point cloud of seat 3 is periodically reduced

Part Number: AWRL6844

Tool/software:

Hi Ti,

  

We've tested the AWRL6844_InCabin_Demos example several times, and the Seat Belt Reminder (SBR) function's detection results for seat 3 are cyclically changing.

When there are four or more passengers, and one person is seated in seat 3, the point cloud for that seat will periodically increase and decrease, causing the recognition results to periodically fluctuate between occupied and unoccupied, with a frequency of approximately 3 to 15 seconds. However, this issue does not occur for other seats.

I'd like to ask if there are any recommended parameters to adjust?

    Hi ED,

    While I assign this E2E to the right person, can you please let us know what is the version of Radar Toolbox and version of SDK that you are using?

    Regards,

    Hi, ED:

    Thank you for using e2e.  We have experienced the same issue.  We have recently scanned AWRL6844 EVM antenna behavior and noticed that the antenna radiation pattern is not symmetrical for this antenna.  You can see from the below figure, the radiation pattern is much lower around seat 3 area.  

    Best,
