Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

I ask question.

Please tell me AWR1843 how to determin the detection.
(Ex.SNR or Range Resolution)

In detail, If you decide by SNR, please tell me quantitatively how much is necessary.

    Hi,

    Can you please provide more details for your question?

    We have the mmWave SDK as an example of demo.

    If you are trying to understand the concept of processing, there is an older version of the SDK that includes documentation that may be easier to understand

    C:\ti\mmwave_sdk_02_01_00_04\docs\mmwave_sdk_module_documentation.html

    Thank you

    Cesar

    I am currently making measurements using the mmWave Demo Visualizer, but I am not sure how to distinguish detected objects, so I would like to ask you a question.

    (postscript)
    I will check the materials you posted.

    Hi,

    The points that you observe in the mmWave Visualizer are detected using the CFAR algorithm.

    You can find a description of the algorithm here

    Constant false alarm rate - Wikipedia

    The detection decision is based on the SNR of the peak in range doppler heatmap and threshold.

    Please review the documentation I mentioned. I think it provides a good overview

    Thank you
