AWR2243BOOST: DCA1000 radarCube data format

user6158104

Part Number: AWR2243BOOST
Other Parts Discussed in Thread: DCA1000EVM,

Hello TI experts,

I got raw data by using "rawDataReader.m" of mmWave Studio with DCA1000EVM from AWR2243BOOST.

The rawDataReader.m  made the radarCube.mat for us.

Could you let me know the data structure of "radarCube.data" and data format of "radarCube.data{ , } in the radarCube.mat?

Conditions are; [2 tx channels], [4 Rx channels], [Format ;Complex 1x], [IQ Swap; I First] , [4 Lane Configuration], [256 ADC samples], [128 chirps/frame], [8 Frames]

Thank you in advance for your kind advice.

    Hi,

    The raw data format is described in

    C:\ti\mmwave_studio_02_01_01_00\docs\mmwave_studio_user_guide.pdf, Section 24.5

    This will help you understand the format read by radarCube.m

    Thank you

    Cesar

    Hi Cesar,

    Thanks a lot for the quick reply.

    However, I believe the format you have pointed out may be one for the adcData,mat, which is also described in the mmWave studio user guide, the section 25.4, for the mmwave_studio_03_0_0_14.

    The "rawDataReader.m" makes two .mat files for us, the adcData.mat and the radarCube.mat.

    My question is about the data format of the radarCube.mat.

    The data structure obtained for the case; 256 samples,128 chirp/frame, 8 frame, are attached for your reference.

    I would appreciate it if you would show the data format clearly for me.

    Again thank you in advance for your kind support.

    Hi,

    In each frame, there are 128 chirps, each chirp has 256 complex samples and there are 4 Rx antennae.

    so for each frame there is 128x254x4 complex samples.

    Does this answer your question?

    thank you

    Hi Cesar,

    Let me double-check my understanding by the attached file. 

    The attached file shows my understanding about the data format.

    Is this correct?

    Thank you in advance.

    Hi,

    I think this is correct

    Please also double check with the script provided to verify the data. It shows how the mat file is parsed.

    C:\ti\mmwave_studio_03_00_00_14\mmWaveStudio\MatlabExamples\singlechip_raw_data_reader_example\verify_data.m

    Thank you
