Part Number: AWR1642BOOST

Dear sir or madam. I use AWR1642BOOST to detect hand movement. When I put the hand in front of the antenna (like the picture), (the first peak in the picture is always appear even I remove my hand) . I use mmwave demo and I cannot see the peak at my location. I know maybe hand is not a good reflector. Anyway can set up the mmwave demo to recognize my hand. Thank you

    Hello Minh,

    Can you please try the cfg file provided as part of the mmWave demo under the profiles directory with the following enabled (uncommented)
    calibDcRangeSig 1 -5 20 256

    This should take care of the peak near the DC range of IF and in turn should allow the peak created by hand reflection be detected better.
    Additionally please check/tweak the CFAR configuration setting which are set in the config file as this decides which peak is marked as an object.

    Details about the above cfg file parameters are discussed in SDK User's guide under "3. 5. Configuration (.cfg) File Format" .

    Typical paths:
    cfg files: C:\ti\mmwave_sdk_01_00_00_05\packages\ti\demo\xwr14xx\mmw\profiles\
    SDK UG : "C:\ti\mmwave_sdk_01_00_00_05\docs\mmwave_sdk_user_guide.pdf"

    Thank you,
    Vaibhav
