IWRL6432BOOST: Range Profile Major, Minor detection

Part Number: IWRL6432BOOST
Other Parts Discussed in Thread: IWRL6432

What is the difference between Range profile Major and Minor detection?

Is there any specific documentation available for the same. 

Any Q format is applied for the Range profile in IWRL6432? 

What is the bandwidth to be considered  for each major minor detection?

  • The range profile is constructed from the maximum of the angle/doppler detections for each range bin. So, the major profile will correspond to faster movements and the minor profile will correspond to slower movements.

    Is there any specific documentation available for the same. 

    The docs in the SDK docs/ folder describe this. 

    Any Q format is applied for the Range profile in IWRL6432? 

    See the python code in the industrial visualizer for decoding the range profile packets. It appears that we simply take 20log10 of the integer value returned in the TLV.

    What is the bandwidth to be considered  for each major minor detection?

    This depends on the time between frames. Calculate this with the 5th and 6th arguments in the sigProcChainCfg

  • If I am trying to take range profile data and consider only some bins for testing with a classification model(user-defined), how would I consider the maximum range for the current profile? which parameters and equations used for the same.?

    If range resolution is 

    then what will be sweep bandwidth considered in IWRL6432 on which chirps?

    what will be the maximum unambguous range?

    how this is distributed to FFT size.? 

  • If I am trying to take range profile data and consider only some bins for testing with a classification model(user-defined), how would I consider the maximum range for the current profile? which parameters and equations used for the same.?

    Maximum range will be dictated by the amount of power the target is able to reflect back to the transmitter (see radar equation) and the maximum range allowed by the chirp. 

    See our sensing estimator tool here to calculate the subsequent values.
