AWR1843AOPEVM: Issue with Automated Parking Application on AWR1843AOPEVM – No Data Displayed in MATLAB

Part Number: AWR1843AOPEVM
Other Parts Discussed in Thread: TIDEP-01026, AWR1843BOOST, AWR1843AOP

Tool/software:

Hello TI Team,

I am working with the AWR1843AOPEVM development board and running the Automated Parking application.

I followed the steps as described in the documentation:
C:\ti\radar_toolbox_3_20_00_04\source\ti\examples\Automotive_ADAS_and_Parking\automated_parking\docs\automated_parking_18xx_users_guide.html

After completing the setup, the MATLAB prompt opened, but no data is being displayed.
For your reference, I have attached a snapshot of the issue.

Could you please advise why this might be happening or guide me on what step I might have missed?

Thank you for your support.

Best regards,
Mitesh

    Hi,

    Please see this document that shows how to run the mmWave SDK demo on the AOP EVM. Since the Parking Demo is identical to the SDK demo, same steps apply

    Thank you

    Hello Cesar,

    I followed the above documentation and was able to run the radar successfully. The data is being displayed on the mmWave Demo Visualizer.

    According to the automated parking application pdf (Design Guide: TIDEP-01026), the radar should be able to detect both static objects (e.g., poles, walls) and dynamic objects such as cars and pedestrians.

    However, during my testing, I noticed the following behavior:

    When a person is standing still in front of the radar within a range of ~10 meters, no points are displayed on the 3D scatter plot.

    When the same person starts moving, the points appear correctly on the 3D scatter plot.


    Could you please clarify:

    1. Is the automated parking demo intended to detect static objects as well, or only dynamic ones?

    Thank you for your support.

    Yes, it can detected static objects. 

    Detecting static objects is the most challenging use case for radar sensors. So detection range is shorter than moving objects.

    The AOP device does not have sufficient power to detect static pedestrians at 10m. 

    For that you would probably need an AWR1843BOOST EVM. 

    Even with the AWR1843BOOST EVM the static pedestrian detection will not be maybe more than 15m

    Thank you

    Hello Cesar,

    According to the TI document AW1843AOP_automated_parking.pdf, the AWR1843AOP is specified to detect static objects at ranges of 10m,15 m or 20 m, depending on the type of object.

    However, in my testing, when I stand within 10 meters of the radar (e.g., at 2, 3, 4, 5, 6, 7, or 8 meters), no detection points appear on the 3D scatter plot.



    for your reference
