AWR6843AOPEVM: I’d like to know if the radar data is being received correctly.

Part Number: AWR6843AOPEVM

Hello, I’m currently using the radar board AWR6843AOP-EVM, and I’m visualizing data in RViz through the ROS2 driver included in SDK 3.6.2.
The file DataHandlerClass.cpp located in the path shown in the first image is attached.

While checking the values sent from the handler class to RViz, I noticed that the velocity values seemed abnormal.

When I output the data in read.object.struct mode, I found that the velocity values only show a few fixed numbers repeatedly.
I’d like to ask whether this kind of output is normal.

I’m leaving this message to ask about this issue.

Best regards,
Woohyun Jeon

Hello,

Thanks for reaching out. I've looped in our ROS driver expert to comment further on the behavior here. Please give them a day or two to respond.

Regards,

Hello Woohyun Jeon,

If you take the configuration file and import it into the mmWaveSensingEstimator, you will get a velocity resolution that will align with what you are seeing with the velocities. Adjusting chirp parameters and implementing performance trade-offs you can definitely get the velocity resolution to be more precise.

Best Regards,

Pedrhom
