2.6 Scene Selection – Best Range Resolution
This section guides users through the sequence of selections they should follow when Best Range
Resolution is selected under the Desirable Configuration menu.
2.6.1 Frame Rate (fps)
This is a slider that prompts users to select the rate at which the measurement data must be shipped out
of the mmWave device.
Effects on other user knobs:
• Controls the minimum value on the Maximum Radial Velocity slider.
• Faster rates limit the number of plots and measurement data that can be captured from the mmWave
device. See Section 2.10 for more details.
CLI command details: defines frame duration (frame periodicity in ms) in the frameCfg command.
2.6.2 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 amount of separation you expect between the detected objects or points in the point
cloud. Because this is the Best Range Resolution configuration, the slider presents options only for the
best possible range resolution for the user-selected frequency band.
Effects on other user knobs:
• Relatively lower or finer Range Resolution selected by this slider provides options for longer Max
Unambiguous Range but lower values for Maximum Radial Velocity.
• Relatively higher or coarser Range Resolution selected by this slider provides options for shorter Max
Unambiguous Range but higher values for Maximum Radial Velocity.
This slider allows for minor tweaking in the centimeter units, to help users attain desired fine tuning of
configuration for the Max Unambiguous Range and Maximum Radial Velocity.
CLI command details: defines frequency slope constant and Ramp end time in µs in the profileCfg.
2.6.3 Maximum Unambiguous Range (m)
This is a slider that prompts users to select the desired Maximum Unambiguous Range in meters. Select
the value based on the farthest distance you expect to see objects detected. See Section 4.3 to
understand the Radar cross section and the actual range at which objects equal to the radar cross section
can be theoretically detected by mmWave technology.
Effects on other user knobs:
• Setting this slider to lower values provides more options for the Radial Velocity Resolution, versus
setting this slider to higher values providing less options for the Radial Velocity Resolution.
CLI command details: defines number of ADC samples and ADC sampling frequency in ksps in the
profileCfg command.
2.6.4 Maximum Radial Velocity (m/s)
This is a slider that prompts users to select the desired Maximum Radial Velocity in meters/second. Select
the value based on the maximum radial velocity you expect targets to be moving in within the radar field of
view.
Effects on other user knobs:
• Radial Velocity Resolution is directly proportional to the Maximum Radial Velocity setting. Setting this
slider to lower values provides finer Radial Velocity Resolution versus setting this slider to higher end
of values provides coarser Radial Velocity Resolution.
CLI command details: defines idle time in µs in the profileCfg command.
