AWR1843AOPEVM: Clarification on Static Object Detection in AoP Parking Application

Part Number: AWR1843AOPEVM
Other Parts Discussed in Thread: AWR1843BOOST

Tool/software:

Hello TI team,

I followed the user guide "automated_parking_18xx_users_guide.html and successfully flashed the prebuilt binary "xwr18xx_mmw_aop_demo.bin" located at:

C:\ti\radar_toolbox_3_20_00_04\source\ti\examples\Automotive_ADAS_and_Parking\automated_parking\prebuilt_binaries in the AWR1843AOPEVM and got the data on the Matlab GUI.

As per Section 3.2.2.1 of the TI AoP Parking Application User Guide the sensor is able to detect pedestrians even when it is in a static condition. (see in the Figure 3-4)

However, during my testing (sensor is static), the radar only detects moving objects and fails to detect a stationary pedestrian standing within 5 meters in front of the sensor.

Could you please help clarify if additional configuration is required to enable static object detection?

Thanks

Mitesh

    Hi,

    In the profile config "profile_parking_mimo_2d_50m_3d_10m_aop.cfg" clutterRemoval is disabled for both frames. This means that you should be able to see static detections.

    clutterRemoval -1 0

    Notice that for the 3D subframe configuration,  the range cfarFOV is limited to about 8.5 meters

    % 3D Subframe Configuration(s)
    guiMonitor 1 1 1 1 0 0 1
    cfarCfg 1 0 2 8 4 3 0 15 0
    cfarCfg 1 1 0 4 2 3 1 15 0
    cfarFovCfg 1 0 0.25 8.64
    cfarFovCfg 1 1 -7.06 7.06
    CQRxSatMonitor 1 3 11 121 0
    CQSigImgMonitor 1 127 8
    Thank you

    Hello Cesar,

    I’m using the same radar configuration you provided, but I'm facing a few issues:

    1. Static objects within 5 meters are not being detected, even though they are well within range.

    2. The GUI freezes automatically within 30 seconds of operation and also faced same problem with mmWave_Demo_Visualizer.

    3. After uploading the configuration, I attempt to capture radar packet data via UART using RealTerm, but no data appears on the interface.

      Thanks

    Hi,

    Do you happen to have a AWR1843BOOST so that you test the same code with a different platform?

    I want to make sure this is not a board issue.

    thank you

    Hello cesar,

    I run the demo (AOP parking) application on the AWR1843AOPEVM.


    "I have tested the MRR application on the same board and was able to successfully capture packet data, which indicates there is no hardware issue."

    Unfortunately, I do not have another board like the AWR1843BOOST.

    Thanks

    Hi,

    I was ablet to run the demo on the AOP EVM today.

    I have run the following visualizer and configuration:

    mmw_demo_parking_xyz.exe xwr1843 38 10 4 37 profile_parking_mimo_2d_50m_3d_10m_aop.cfg 1

    Please see my feedback below

     

    1. Static objects within 5 meters are not being detected, even though they are well within range.

    [Cesar] The snapshot below shows that I was able to detect static objects at a distance larger than 5m. If in your usecase you are not able to detect them, this means that the SNR is not sufficient.

             2, The GUI freezes automatically within 30 seconds of operation and also faced same problem with mmWave_Demo_Visualizer.

    [Cesar] In my testing, I noticed one time that the GUI froze. This did not happen all the time. I am running the GUI for 15min and it still runs. This is caused by matlab high gui processing when there are many detections. One way to improve this is to reduce the number of detected points. There may be ways to optmize the gui code. You would need to check with matlab support forum. Unfortunately the team that developed the GUI is no longer available for support. So, there is no additional support we can provide on this  

            3. After uploading the configuration, I attempt to capture radar packet data via UART using RealTerm, but no data appears on the interface

    [Cesar] We are not familiar with this tool. Please check with tool developers for support

    Thank you
