<p><span style="font-size:13.5pt">They did. They use NEC4 (if I remember correctly). It is just classic array physics - just big at these frequencies. The physics is the same for the nifty flat panel radar arrays or curtain dipole arrays like we use in
HF broadcasting. They just have some very cool software to change the transmitter exciters to provide beam steering, circular polarization, and lots of other cool stuff. Each dipole has its own transmitter. 180 cross dipoles with 360 10 kW transmitters.
