IWR1642: How far can IWR1642 support distance(m) By pplcount gui program?

Part Number: IWR1642

Hi,

Now I try to test IWR1642 by pplcount gui program, about support distance.

please reply below question,thanks

1. the max distance support is (M)?

2.I had use your config mmw_PC_14m_Hallway,test result the distance about 14m

   we want to test 40m , after refer your documount , I had change some parameter 

   profileCfg 0 77 30 7 62 0 0 9 1 128 2500 0 0 30

   AllocationParam 20 0.01 5 1 2

   StateParam 2 5 10 100 5

   After test , the distance result about 20m.

   So ,please suggest how can i to achieve 40m distance?

Thanks very much

    Hi Melvin,

    The longest distance at which you can get a detection will be mostly effected by the chirp.  Generally, when designing the chirp, you will want to extend a few meters past your maximum range.  Based on what you have changed in the configuration, it appears that you have read our tuning guide. If not, you can find it here.

    If possible, could you attach a picture of the point cloud output from the device when the target is close to max range? The point cloud values (range, azimuth. doppler, SNR) would also be useful.  I am trying to determine if the point cloud needs to be improved by modifying the chirp, or if the GTrack parameters need further tuning.

    Regards,

    Justin

    Hi,
    Thanks for your reply.
    I will try to change configuration , then discussion with your .

    Below question need your reply.
    1.The IWR1642 hardware RF desige  achieve the max distance is(M)?
    2.Now, IWR1642 with pplcount program optimize stable distance is 14M(reference your document) or ?
    3.If we want to achieve 40m distance ,maybe  designing the chirp  ,it will be  achieve?

    Thanks very much
