AWRL6432: When changing TX/RX configuration, does RADAR processing code needs to be modified?

Part Number: AWRL6432

Tool/software:

Hello team,

When running our examples on SDK and/or Toolbox, usually our Visualizer displays point cloud. When user wants to modify TX/RX channel configuration, do they need to modify RADAR processing chain as well? Or, is it something user doesn't need to care about when changing TX/RX channel configuration?

Regards,

    Hi, Victor:

    Does TX/RX channel configuration mean the antenna layout change or enable different TX/RX channel in the TI EVM board?

    Different demo may be different in term of flexibility. Which demo are you talking about here?  

    Best,

    Dear. zigang

    This is Simon from LGIT.

    I'm planning to review the demo using the TI EVB (AWRL6432BOOST, planned purchase).

    I intend to evaluate the 1Tx – 3Rx functionality in the parking motion detection feature (Exterior Intrusion Monitoring with AWRL6432).

    I would like to inquire if this functionality can be configured.

    Regards,

    Simon. Ha

    Hello Zigang,

    Thanks for your comments. As Mr. Ha mentioned above, they used Exterior Intrusion Monitoring example. Your further comments would be appreciated.

    Hi, Victor:

    Is the exterior intrusion monitoring example the intruder detection demo in radar toolbox?  https://dev.ti.com/tirex/explore/node?node=A__ANK5TVs-nTCewg8GyAbdqg__radar_toolbox__1AslXXD__LATEST

    The intruder detection demo is based on motion and presence detection demo in SDK L.  You can find the users guide at:

    file:///C:/ti/MMWAVE_L_SDK_05_04_00_01/docs/api_guide_xwrL64xx/MOTION_AND_PRESENCE_DETECTION_DEMO.html#autotoc_md777

    You may need to change the version number to match your download version. 

    This motion and presence detection demo support 1 TX * 3 RX case. 

     

    Therefore, changing the chirp configuration CLI should enable just 1TX3RX case. 

    • Set RxChCtrlBitMask = 7, and TxChCtrlBitMask = 1 in channelCfg (assuming enable TX1 and disable TX2)
    • Set ChirpTxMimoPatSel = 0 in chirpComnCfg
    • Set NumOfChirpsInBurst = 1 in frameCfg

    Best,
