Compiler/IWR6843ISK: How to get 3D point cloud data from IWR6843ISK

Hello,

Please download and install MMWAVE-SDK 3.1.x from http://software-dl.ti.com/ra-processors/esd/MMWAVE-SDK/latest/index_FDS.html. Look for instructions on how to run the SDK Out of Box Demo in C:\ti\mmwave_sdk_03_01_01_02\docs\mmwave_sdk_user_guide.pdf  under Section-1 Out-of-box mmWave Experience. The Out of Box demo provides a 3D Point Cloud over UART which is visualized in the mmWaveDemoVisualizer.

After this, you can refer to the mmWave SDK demo doxygen documentation under C:\ti\mmwave_sdk_03_01_01_02\packages\ti\demo\xwr68xx\mmw\docs\doxygen\html\index.html to understand the UART output format and decode it using your own Matlab script or application. You can also download the mmWaveDemoVisualizer source code and refer to the function process1 in mmWave.js to understand the parsing.

Hello,

To get 3D point cloud in mmWaveDemoVisualizer, you need to select the 4RX, 3TX Antenna Configuration as shown in the picture below. The maximum detection range depends upon factors such as type/shape of object (RCS), chirp configuration, antenna gains etc. Please refer to the following resources to understand the maximum detection range:

1. App note: mmWave Radar Sensors: Object Versus Range
2. E2E thread: IWR6843: Is the IWR6843 suitable to detect items between 20mm and 500 mm?
3. E2E thread: IWR1443: Generic development flow to define/implement the RF and DFE configuration for the specific application (this thread talks about the mmWave Sensing Estimator which you can use to define chirp configurations based on application requirements such as range, velocity etc)
