WEBENCH® Tools/IWR1443BOOST: mmWave Studio + IWR1443 + DCA1000,process the raw data

dx y
Prodigy 90 points
Part Number: IWR1443BOOST

Tool/software: WEBENCH® Design Tools

1 . I'm using IWR1443BOOST  to capture raw data, and doing post processing in MATLAB.

But angle calculation error is very large; it is displayed normally on mmWave Studio, as shown in the figure below: there is an angle reflector at 1m, 0 ° azimuth;

When I use matlab to process the original adc data, the angle is calculated as about 4 °. Is the phase compensation performed in PostProc of mmWave Studio?;

2. Can you give me the code of PostProc of mmWave Studio for reference?  want to know how mmWave Studio processes the raw data；

Thanks ！

    HI, 

    For your first question:  The post processing in radar studio does not compensate for phase offset.   In order to estimate phase offset, you need to run the SDK out-of-box demo.  Please read through section 6.8. at C:\ti\mmwave_sdk_02_01_00_04\docs\mmwave_sdk_user_guide.pdf  

    For your second question: 

    There is an example MATLAB script for post processing located at: C:\ti\mmwave_studio_02_01_00_00\mmWaveStudio\MatlabExamples\singlechip_raw_data_reader_example

    You can go through the readme.txt first.

    Best,

    Zigang
