AWR1843AOPEVM: Detect the maximum distance by AWR1843AOP

Part Number: AWR1843AOPEVM
Other Parts Discussed in Thread: AWR1843AOP, AWR1642, AWR1843, AWR1843BOOST, AWR1642BOOST

Hi,

  I try to use the mmWave Demo visualizer for AWR1843AOPEVM, but in the web the max range just is 50m.I find some article that say the max range is more far.How can I test that?

Thanks,

charles

    Hi,

    The maximum range is dependent on

    • what type of object one is trying to detect
    • chirp configuration
    • how many tx antennae are enabled - is MIMO TDMA being used or are all Tx enabled at the same time?

    We have performed some tests with AWR1843AOP and with MIMO TDMA configuration, we have detected cars at a maximum range of 50-60m

    Thank you

    Hi,

      Thank for you respond,how far could AWR1843AOPEVM detect maximum range of child and adult, and, are AWR1843's and AWR1642's results the same?

    Thank you

    Hi,

    With MIMO TDMA configuration one should be able to detect a moving adult 20-25m. We have not tested with child

    When enabling all Tx at the same time (Beamforming) the maximu range should increase. Probably around 40-45m at lease but we have not tested.

    The AWR1642 and AWR1843 do not have integrated antenna. With the antenna provided on AWR1843BOOST EVM, for MIMO the performance should be a little better. For adult detection I would expect 30-35m

    Thank you

    Hi,

    In mmWave Demo Visualizer,is the selection of the 4Rx,2Tx below the image enabling beamforming?

    Thank for 

    Charles.

    No,

    For beamforming you can evaluate the MRR demo

    https://dev.ti.com/tirex/explore/node?a=VLyFKFf__1.0.4&a=VLyFKFf__4.8.0&node=AObIl5yAPR-DjIwxgdgyuA__AocYeEd__LATEST

    You would need to download and unzip the entire mmWave Automotive toolbox.

    thank you

    Hi,

    I tried to open MMR demo, but it showed up on the CCS that it was only for 18XX. How can I use it for AWR1842AOP or AWR1642?

    I find SSR demo which include SRR80.h and SRR120.h. Does those enable beamforming?

    Thank for

    Charles

    For AWR1642BOOST you can use the SRR demo. It enables beamforming

    For AWR1843AOP, you can run the MRR demo.

    By default the MRR demo supports MRR and USRR subframes. You can rebuild the demo to support only MRR subframes.

    \labs\lab0007_medium_range_radar\src\common\mrr_config_consts.h

    Update as follows

    /**! @brief The multi-mode Radar mode of operation. */
    //#define SUBFRAME_CONF_MRR_USRR                   /* Two subframes, MRR followed by USRR20. */
    /**! @brief The USRR only mode of operation. */
    //#define SUBFRAME_CONF_USRR                   /* One subframe USRR20. */
    /**! @brief The MRR only mode of operation. */
     #define SUBFRAME_CONF_MRR

    Thank you
