The RBE-2 AA picture released yesterday by Thales has raised a polemic all around the web. Indeed, the number of modules of the presented antenna is exacly 838, which is almost 20% less than the usually advertised "1000 modules" for this radar.
However it is not known if the picture shows the actual radar. It could be an earlier prototype or a dummy. One thing is sure, though: it is exactly the same antenna (same pattern) as the one shown in the previous pictures of the RBE-2 AA.
The graph on the left is illustrating the asymmetrical pattern of the modules and the number of modules on each of the 36 columns of the antenna.
