Abstract

A system for providing broadband interference and allowing communication there through, the system comprising: air interference transmitter for transmitting an interference signal, the interference transmitter having a transmitter feeder and a first antenna; a radio receiver for receiving a radio signal, the radio receiver having a radio feeder and a second antenna collocated with the first antenna of the interference transmitter; a steering signal generator for introducing at least one steering signal into the interference signal at the transmit feeder; sampling means for sampling a portion of the interference signal that includes at least one of the steering signals; adjusting means for adjusting the amplitude and phase of the sampled portion of the interference signal; and first coupling means for coupling the adjusted sampled portion of the interference signal into the radio feeder.
