摘要
The present invention is directed to a multibeam antenna reflector distortion compensation system comprising at least one remote reference radio frequency transmitter cooperating with a feed cluster of a beam forming network which includes one central and at least two peripheral feed elements, means for producing error signals including a circuit for consecutively connecting each peripheral cluster feed element to one input of an adding circuit, and the central feed element to the other input after appropriate attenuation and phase compensation of the central feed signal, and means for down-converting linear and non-linear distortion correction signals based on the down-converter output.
