But from what I know Herakles should be one-panel only.

You know the picture with the large horn.....not very convincing leh.Originally posted by sane_guy2:But from what I know Herakles should be one-panel only.

The horn is suppose to 'ease' the RF into open space right? Some form of impedance matching?
Tot it is outdated by now. -
It depends on whether Herakles is Active or Passive phased array. I think the chinese juornals say it is passive, so assume it is.
Then for passive array, you need to use waveguides to connect the antenna array (that is the "panel" structure you see on the flat surface) to the electronic devices which are situated AWAY from the antenna. The said electronic devices are transmitters and receivers (Tx/Rx).
It horn structure is nothing like "horn antenna" or is it dedicated impedance matching, but it is just "casing" covering the bunch of waveguides leading away from the radome to where ever the Tx/Rx is.
If it is ACTIVE phased array, then that means the electronics are situated TOGETHER with the Antenna elements, this is the very meaning of ACTIVE PHASED ARRAY. SO then it is obvious that immediately behind the "antenna panel" will have to be all the electronics. In this case, the horn structure is just a housing for electronics. -
Thanks for the info.
Say it's a passive array......the arrangement of the waveguides (from the shape of the housing) seems unconventional and not very efficient (waveguide routing) to me.
My guess is that picture isn't 'accurate'.....
Well, let's wait and see then. -
