Relatively interesting project. I see main challenge in maintaining an active community, with good working application examples. They probably should have designed antenna differently, at least changed RX spacing in elevation plane to increase unambiguous monopulse angle sensing. There are numerous commercial modules that copied
AWR6843ISK evaluation kit antenna arrangement.
update 1: Some other modules using similar chipset, search for AWR6843 / IWR6843:
watching on it, such interesting
Why not make full high resolution 2D phased arrays or reflect-arrays at this point? (Or transmissive equivalents of reflect arrays.) RF PIN diodes are cheap, Dishy did it.
Wassenaar?
I think that RadarIQ was an attempt to create a hobbyist friendly version of original TI's 60GHz evaluation board, certainly not an alternative to
Echodyne or
Metawave radars. Good attempt, but community is too small and there are no news on the project.
