Abstract: A jammer for generating and transmitting RF broadband jamming signals for jamming one or more local RF receivers. The jammer includes a broadband antenna unit for receiving broadband RF jammer received signals from local transmitters and for transmission of regenerated broadband RF jamming signals to the local receivers. The jammer uses a plurality of jamming algorithms including a regeneration algorithm and one or more alteration algorithms that alter the regenerated signals whereby the altered regenerated signals are asynchronous with respect to ones of, or all of, the jammer received signals. The alteration algorithms include a chopping algorithm and an FM modulation algorithm.

Abstract: A digitally controlled angle noise signal generator for generating a signal with precise and accurate noise. The signal generator is formed of a digital noise generator for generating a digital noise signal &thgr;N, and a digital signal generator for forming an internal signal S. The digital signal generator receives the digital noise signal &phgr;N and modulates the internal signal S with the digital noise signal &phgr;N to generate a digitally controlled signal yg=S{&thgr;N}, where is the modulation operator, with precise and accurate noise.
