DCA1000EVM: Deriving various parameters from RAW Data captured from AWR1443BOOST using DCA1000EVM

Aabid Farooq

Part Number: DCA1000EVM

Hi,

i am working on mmwave devices and i am successfully ran the out of the box demo. 
I also captured the RAW data using DCA1000 and imported the file into matlab for further processing. 
while searching for information regarding the RAW data format i was able to determine that the values in the RAW data file correspond to the amplitudes of the received signal at the time instant.
Now the issue i am currently facing is how to calculate different parameters from these amplitude values. Kindly help with understanding this data and what mechanism/formulas to use so as to derive different parameters so that i can represent the data graphically like demo visualizer.

Regards.

Aabid Farooq.

    Hi,

    After Capturing the Raw Data you would need to develop matlab or python code to process this data. The main steps of this processing are range FFT, doppler FFT and angle FFT.

    Our group does not provide matlab code. We only provide code implemented on target. You would have to develop the matlab code

    thank you

    Hi Cesar. Thank You for your quick response.

    Is there any documentation available that can help me understand how to do processing for Range FFT, Doppler FFT and angle FFT?
    Also once these steps are done do i need to simply plot data?

    and if i want to lets say measure the distance of a detected object, how can that be achieved?

    Regards.

    Hi

    I think you should start by watching our mmWave Fundamentals training.

    After that it would be helpful to consult a Radar Signal Processing textbook to understand the fundamentals of how fft is used to determint range, velocity, angle.

    Then, you should look at the mmWave SDK OOB demo. It implements in C the algorithm

    Thank you

    Thank You for your responses Cesar.

    Can you please name a book that can help me understand the concepts very well.

    Thank You.

    If you search "radar signal processing" on the web you should find several textbooks available

    thank you
