AWR1642BOOST: AWR1642BOOST

Part Number: AWR1642BOOST

Hello Team,

I am trying to understand the difference between unprocessed data and processed data after the post processing button is clicked in mmwave studio

Is there any documentation that explains that. I did a quick search in the forum but all I came across was that no code would be shared from TI (Not sure if the status is still the same). I am interested to know the functional changes so that I can better explain the ghost images and unnecessary detections on my end on the processed data and not on the raw data.

Thanks

Subhash

    Hi,

    Thank you for your questions.

    There are two things that happen during mmwave studio post processing button

    Step#1 - Packet re-order and zero fill (see mmwave studio UG section 3.2). The result of Step#1 is the actual raw data

    Step#2 - After Step #1 is complete, a set of matlab routines are run on the data. The matlab routines are basic range fft, angle estimation...

    Thank you
    Cesar

    Hello Cesar, I am not sure if I follow... My question is Is there a difference between IQ data stored in Raw bin file VS IQ data stored in processed bin file.

    Please read the mmWave Studio UG as I mentioned. Section 3.1 and 3.2

    In order to remove the packetization headers from the files generated by the DCA1000 board, one needs to run the packet re-order and zero fill utility. THis utility will remove the headers and will generated the raw data file that is post processed by matlab.

    SO, I think that with your terminology "IQ data stored in Raw bin" this is the data generated by DC1000 board. this data includes headers, it is not the raw data ready to be processed by matlab

    " IQ data stored in processed bin file" this is the data after running the packet re-order and zero fill utility. This is the data ready to be processed by matlab.

    I hope that this is clear.

    Closing this thread now. If there are new questions please open a new thread

    thank you
