1. A system for simultaneously handling a communication signal with a jamming signal comprising:

  • (a) a jamming signal generator for generating a jamming signal of a desired type;

    (b) a local oscillator (LO) for generating a local oscillator signal of a desired frequency;

    (c) a double-sideband suppressed carrier modulator for modulating the jamming signal into a modulated jammer signal having two sideband components with local oscillator frequency rejection thereby forming a steep notch between them encompassing the local oscillator frequency; and

    (d) a communication signal antenna and circuitry for handling a communication signal modulated at or near the local oscillator frequency and positioned within the notch formed between the sideband components of the modulated jammer signal, thereby enabling jamming simultaneously with handling of the communication signal.
