Part Number: IWR1843BOOST

Tool/software:

After post-process there is file created with a type BIN file, may i know what does the data mean? or what is the content of the BIN file

    Hello, 

    For DCA1000, after pressing "DCA1000 ARM" and "Trigger Frame", raw data file called adc_data_RAW_0.bin is saved first. Due to the Ethernet protocol, the file received by the DCA1000 EVM may not contain the UDP packets in correct order. There could be scenarios when the data is missing and not captured in the file. The packet reorder and zero fill utility needs to be run to scan through the raw captured file and re-arrange the packets in correct order and in case of any missing packets; it will fill an equal amount of zeros in the file. This utility also removes the meta data and the output now contains the raw ADC data as transferred by the xWRxxxx device. By pressing "PostProc" button, adc_data_RAW_0.bin will go through packet reorder and zero fill and is saved as adc_data.bin. Same result can be obtained by running the Packet_Reorder_Zerofill.exe, as instructed in the Mmwave Studio User's Guide. 

    Best Regards,

    Thank you, but sorry to ask you again, is it the ADC data in the BIN file does not contain anything? or is it the radar signal that we need to organized it back to readable format or spectrogram?

    Hello, 

    Can you please clarify what bin file you are talking about. I assumed you meant the BIN file collected with mmWave Studio and the DCA1000. Is that correct?  If so, then yes the bin fil contains the raw adc data samples. The data format is described Interpreting RAW Data section of this guide.

    Regards,

    Hello,
    Yes that's data I mean, so is it the ADC data? and what are the useful of ADC data? is it we need to spectrogram to analyze the data?

    Hi, 

    The ADC data is the raw digitized signal output coming from the ADC and it is available in the ADC buffer. The demo code running on the device does additional processing on these ADC samples to identify detections but using mmwave studio and a DCA1000 you can capture the unprocessed ADC samples. This can be useful for developing and testing advanced processing algorithms. 

    Best regards,
