AWR1843AOPEVM: AWR1843AOPEVM Can Communication

Tool/software:

Hello Officer, 

I am using medium range radar example of awr1843. My aim is to send track information such as range and velocity of tracked objects via Can protocol. Could you provide assistance to accomplish this requirement. 

As you can see the image in below, there isn't track information TLV which is d3h. How can I send ? I tried but I couldn't

Best Regards.

    Do you have any moving objects? Is it a static environment?

    Hello Samhitha,

    Yes I have moving objects, and I have tried to create track movement to observe.

    Hi Serhat,

    Does the Radar operate in MRR or USRR or MRR-USRR mode? Can you provide a breakpoint in MRR_DSS_SendProcessOutputToMSS to check if obj->numActiveTrackers is greater than 0? MRR_DSS_SendProcessOutputToMSS function is present in medium_range_radar\src\1843\dss\dss_main.c.

    Tracker TLV will be transmitted only when processingPath is MAX_VEL_ENH_PROCESSING i.e MRR is enabled.

    Regards,

    Samhitha

    Hello Samhitha,

    First of all, I would like to thank you for your interest. 

    I have configured the radar for MRR operation, but I’m having trouble understanding the output of the Tracking TLV. Are these parameters simply the x and y position coordinates and the velocities in the x and y directions? Do I need to calculate the actual range and radial velocity of each tracked object from these values, or am I misunderstanding something? I only want to send the tracked objects’ range and velocity information; all other values can be discarded.

    Also I wonder that why awr1843aop's project hasn't Ransac algorithm. Could you please provide information about that ?

    Best Regards,

    Hi Serhat,

    You can check getTrackers function in C:\ti\radar_toolbox_<ver>\tools\visualizers\MRR_GUI\read_lvds_out_file_and_plot_object_location.m to parse tracker TLV.
