Part Number: AWR1843
Other Parts Discussed in Thread: MMWAVE-SDK, DCA1000EVM

Hi

Once every 2.5 seconds to 5 seconds (500 to 1000 frames), there is a problem that false positives occur at all distances of the radar,

and we are investigating.

How to solve it?

Thanks and Best regards,

HaTa.

    Hello HaTa,

    Could you provide more info? Which application (mmwave SDK demo or TI-Rex lab)? If any of these then default application or with some modification? What is configuration used?

    Regards,

    Hi Jitendra

    I put customer's feedback below:

    > Which application (mmwave SDK demo or TI-Rex lab)?

    --> MMWAVE-SDK 3.01.00.02.

    > If any of these then default application or with some modification? What is configuration used?

    --> We modified from MMWAVE-SDK 3.01.00.02. We are using the configuration of two or three advanced frames.

    Thanks and Best regards,

    HaTa.

    Hello HaTa,

    There can lot more reason for this behaviour. Have they tried default mmw demo (without any change) with new configuration (2/3 advFrame)?

    And on other side they can try same configuration with mmwave studio to capture the RAW ADC data (using DCA1000EVM) and post-process using inbuild Post-proc tool of mmwave studio to verify this discrepancy.

    Regards,
