6.1 Calibration

The device calibration can be divided into two parts:

  • Factory calibration
  • Antenna calibration

Factory calibration is performed to mitigate the process and temperature effects on the radar analog performance. The Factory Calibration Flow can be understood by referring to the ‘Section: Factory Calibration’ in the mmwave_dfp_user_guide.pdf.

All the related application notes for calibration are shown below, which provides an in depth explanation of all the calibrations in the mmWave sensors.
