2.7.4 Range Resolution (m)

This is a slider that prompts users to select the desired range resolution in meters. Select the value based on the minimum separation you expect between the detected objects or points in the point cloud.

Effects on other user knobs:

  • Relatively lower or finer Range Resolution selected by this slider provides options for shorter Max Unambiguous Range.
  • Relatively higher or coarser Range Resolution selected by this slider provides options for longer Max Unambiguous Range.

CLI command details: Range Resolution and Max Unambiguous Range define the number of ADC samples, frequency slope constant, Ramp end time in µs, idle time in µs, and ADC sampling frequency in ksps in the profileCfg command.
