1. A method for operating a phased array antenna system, comprising the steps of:

  • receiving propagating energy at multiple antenna elements;

    setting control signals for forming the received energy into multiple beams;

    embedding coding parameters into the control signals;

    applying the encoded control signals to at least one phase and gain control device associated with each antenna element to form multiple encoded beams;

    combining the encoded beams into a combined signal; and

    decoding the combined signal to separate the beams.
