Just a guess, but maybe it deals with the Wullenweber [or Wullenwever]

Actually, unlike Wullenweber, they have multiple concentric rings of
verticals in the array with a complex phasing system. My guess is that
this may have been a contributor to the methods eventually used in
phased array radars. But also something that was an engineering study,
and not necessarily practical.
