DCA1000EVM: Instruction manual for mmWave Studio

DCA1000EVM： 2D-FFT raw data

user5874743

Part Number: DCA1000EVM

Can I use  the mmWave Studio API in conjunction with the DCA1000 to get 2D-FFT raw data or 2D-FFT image data?

    Hi,
    Could you elaborate your question here?

    The PostProc script provided with mmWave Studio does all of signal processing (1/2/3-D FFT) which you can use to process your data.

    I can get the adc_data.bin file through mmWave Studio and get the time domain data of the four receiving antennas through the Matlab function readDCA1000 ('adc_data.bin') provided by TI. How can I get the 2D-FFT spectrum? Can the raw data of the 2D-FFT spectrogram shown in the figure below be obtained? Which script under the PostProc folder can get the 2D-FFT spectrogram?

    Hi,

    WIth DCA1000 you can get the raw adc data.

    This data can either be processed

    (i) with embeded Matlab Code. In this case, the output is displayed in the mmWave Studio tool. 2D FFT and heatmap data is not provided to user.
    (ii) with own Matlab Routines


    If you use your own Matlab routines then you have access to the intermediate 2DFFT and Heatmap

    thank you

    Is there an algorithm for solving 2DFFT and Heatmap algorithms?Is the source code for PostProc script available? Thank you

    The matlab postproc script is not available. It is integrated in mmWave Studio.

    2DFFT and Heatmap calculations are standard algorithms described in textbooks.

    The documentation for the mmWave SDK demo is also a great resource to understand and implement the algorithms.

    please see
