AWR1642BOOST: AWR1642BOOST

Part Number: AWR1642BOOST

Sir,

 Is there any theoretical formula to get range from range profile?

I'm able to extract the range profile values, but facing problem to extract the range.

Regards,

Sandeep

  • Hi,

    In the device, we use the following method to compute the rangeResolution.

    dataPathObj->rangeResolution = MMWDEMO_SPEED_OF_LIGHT_IN_METERS_PER_SEC * profileCfg.digOutSampleRate * 1e3 /
    (2 * profileCfg.freqSlopeConst * ((3.6*1e3*900)/(1U << 26)) * 1e12 * dataPathObj->numRangeBins);

    And the rangeIndex can be converted to a distance by multiplying it with the rangeResolution.

  • Please follow this e2e thread, where you need to use mmwaveBeta tool which capture data into x/y/z format.

  • Sir,
    This is an online tool, can you provide me the solution where we can parse the individual range or the X/Y/Z data for further processing?
    PS: I've already used the parser file mentioned, but that doesn't solve it.
  • I'm unable to derive these values from the device and it seems too complicated. Any easier method? Or how to get these values as they are arent specifically mentioned anywhere except by debugging the code, which is a heavy task(namely the sample rates and freqSlopeConstant etc)
    Is there any data descriptor for mmW SDK 03_00_00_08, that'll contain the detected object's descriptor which will help me to parse the value of X,Y,Z , range index etc.
  • Hi Sandeep,

    The information you are looking for is already included in the data that is sent out over the UART and the way to parse the data we send out is clearly documented in the SDK documentation.

    An example for a parser for the recorded .dat file has already been provided to you in other threads.

    Please go through both of these and see if they fit your needs. I'm afraid we cannot do more than this for you.

    Best Regards,
