AWR1443: problem about velocity in demo Zone Occupancy Detection

Part Number: AWR1443
Other Parts Discussed in Thread: UNIFLASH

Hi,

I currently run the demon in AWR1443 for Zone Occupancy Detection. The result in .csv file just like below

I am confused about the velocity in the sixth row, since the number is too high(16829 or 16828).

and I also think that the velocity should have a direction(towards the radar or not). Is something wrong here?

Thank you.

Li

    Hello Li,

    That's unexpected - it should be doppler and signed in m/s. Are you using the precompiled binary provided with the lab to flash the device?

    Hi Amanda,

          Thanks for reply.

          If you mean to flash the device like the step below using uniflash. Yes, I have done that.

    And also can you tell me the algorithm you use in the board to get X,Y,Z and velocity ?

    The point cloud properties are reported by the device when the out of box demo is being run. There is no algorithm in the visualizer to generate x,y,z or velocity. The visualizer is just parsing the data reported by the device.

    To understand the processing chain of the out of box demo please refer to the demo documentation usually located at: C:/ti/mmwave_sdk_03_00_00_08/docs/mmwave_sdk_module_documentation.html
