HI, Jarmo:

Can you explain the picture, what is y-axis and what is x-axis? Usually from linear power to dBm is 10*log10(linear_power).

Best,

Zigang

Hello,

X axis is time. Y-axis is the ampitude value of the point cloud data. The data value seens not linear, nor it is 10*log10(linear power).

Hi, Jarmo:

You will need to look at the data format of the point cloud data to understand that. You can find this information at SDK doxygen documentation located at:

file:///C:/ti/mmwave_sdk_03_04_00_03/packages/ti/demo/xwr68xx/mmw/docs/doxygen/html/index.html#output

Best,
