Question:

I enabled both rangeAzimuthHeatMap and rangeDopplerHeatMap in the guiMonitor line as follows:

guiMonitor 0 0 0 3 1 0 0 0 0 0 0

However, only the rangeAzimuthHeatMap is being output.
I noticed in the documentation and demo notes that rangeDopplerHeatMap is marked as not used in the current SDK.

My question is:

  • Is it possible to enable and output both rangeDopplerHeatMap and rangeAzimuthHeatMap simultaneously using the current SDK version?

  • If not supported by default, is there a way to enable rangeDopplerHeatMap by modifying the source code ?

  • Which specific module or processing chain should be updated to enable rangeDopplerHeatMap output?

Thanks in advance for your guidance.

  • Hi,

    It is not possible to get both range doppler and range azimuth heatmap simultaneously. Only the mmwave demo provides the range doppler heatmap and only the motion and presence demo provide the range azimuth heatmap.

    Use the mmwave demo if you want the rangedoppler heatmap.

    Best
