AWR1843BOOST: Questions about SNR unit in the ROS Driver

Part Number: AWR1843BOOST

Hello!

When using the ROS engine to generate a millimeter-wave point cloud, the information displayed by the point cloud includes x, y, z, intensity, and velocity.

By reading the DataHandlerClass.cpp file, I think that the intensity here refers to SNR. But this code confuses me:

RScan->points[i].intensity = (float) mmwData.sideInfo.snr / 10.0;   // Use snr for "intensity" field (divide by 10 since unit of snr is 0.1dB)

My question is: does this mean that the obtained snr value of a point is one tenth of the actual snr value? (For example, if the snr value of a point is 15db, then the actual snr of that point is actually 150db?)

Best Regards,

Longyi
