AWR1642BOOST: a problem about radar data processing chain

Part Number: AWR1642BOOST

Hello all,

I have an AWR1642BOOST and want to verify my algorithms of pedestrian recognition. The input data that I need for my algorithms is wideband echo data of each target, which means extended target, not a point target. I have read the document "Millimeter Wave (mmw) Demo for XWR16XX " at "C:/ti/mmwave_sdk_02_00_00_04/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html" which explains the processing chain, but I was confused, the document seems out of sync with the code. According to the document, output packets with the detection information are sent out every frame through the UART. Is this output packets exactly the extended target data that I want?  And I searched the "MMWDEMO_OUTPUT_MSG_DETECTED_POINTS)" in the code of "dss_main.c", it doesn't exist. All I want is to save the wideband echo of each extended target to the host for later use. Could you please help me? Thanks a lot!

Best wishes,

Kathy

    Hi,

    The documentation reflects correctly the data output from the sensor. This data is the point cloud.

    Please review the format to understand what the structure of this data is.

    For you project you may need to save this data for several frames on your host and post process it

    thank you

    Hi Cesar,

    many thanks for your reply. The problem is that the documentation doesn't correspond with the code. I searched the MMWDEMO_OUTPUT_MSG_DETECTED_POINTS in the code, it doesn't exist, so I can't understand the data structure well. What 's the name of this output packets with the detection information in the latest code version? Is there any simple way to save this data, or I need to write code to save this data by myself? I noticed that in the Visualizer configuration there is a "Record&Replay options", is this option for this use? Could you please give me any help or suggestions? Thanks a lot.

    Kind regards,
    Kathy
