AWRL6432: CPD With Classification CFAR detection

Part Number: AWRL6432

Tool/software:

Hi, in CPD With Classification User Guide there is a explanation of dimensionality reduction of 3D range-azimuth-elevation arrayto 2D range-azimuth array before CFAR. It says:

The 3D range-azimuth-elevation heatmap is treated as a 2D heatmap with azimuth and elevation dimension reduced to one dimension (angleInd = azimInd + elevInd * azimDim).

Have i understanded correctly, if range-azimuth-elevation has dimensions [N_RANGE, N_AZIMUTH, N_ELEVATION] it will be reduced to [N_RANGE, N_ELEVATION*N_AZIMUTH] where for each range, we will have azimuth spectums from each elevation index appended to one array?
