Bartlett Beamforming function

[CRalli1]

Hi ,
I have been using your Bartlett Beamforming function to extract range and azimuth information from a datacube collected from a DCA1000evm with a 1642BOOST but I have received a strange output where every other range bin is 0. If I remove these range bins I get an image that looks better, but for some reason, the 'hot' patches in the heatmap don't really line up from bin to bin. Any idea why this might have happened? (It is consitent for hundreds of frames)

I have attached images of the heatmaps below

This one is the direct output- every other range bin is 0.

This one has had every other range bin removed, but the areas where the radar ahs detected an object don't line up.
