 RF power is generated by two transmitters and is fed to a power dividing network and then illuminated to the reflector via a waveguide assembly and feed array, creating a group of individual beams stacked vertically to form a wide cosecant squared pattern.In reception, both individual and combined beams are employed, 11 beams are formed by a receive network connected with an 11 channel diversity receiver.The received signals are sequentially mixed, amplified, detected and finally sent for data processing.
