Abstract: A method for synthesizing a wideband signal includes: generating a plurality of narrowband radio frequency signals; and constructively superimposing the narrowband radio frequency signals. In one aspect, this includes determining the delays for a plurality of constituent narrowband signals for use in synthesizing a wideband signal. The delay determination is software implemented, and thus may be embodied in software encoded on a program storage medium and a computing apparatus programmed to perform that method. An apparatus for synthesizing a wideband signal includes: a pulsed power source; a plurality of narrow band radio frequency source modules capable of receiving a signal form the pulse power source and outputting constituent narrowband radio frequency signal; a combiner for combining the constituent narrowband radio frequency signals after they have been uniquely delayed into a synthetic wideband radio frequency signal.

Abstract: The present invention is, in one aspect, a radio frequency source, comprising a gyromagnetic precession oscillator. In a second aspect, the gyromagnetic precession oscillator comprises a closed, non-magnetic, cylindrical outer conductor defining a cavity therein; an axial field solenoid wound about the outer conductor; a non-magnetic, cylindrical inner conductor disposed within the cavity and coaxially aligned with the outer conductor; a plurality of cylindrical ferrite precessors, each defining a respective bore through which the inner conductor runs; a plurality of dividers disposed within and defining a resonant chamber in the cavity; and a dielectric material filling the cavity. In a third aspect, the radio frequency source is actively tunable. In a fourth aspect, the radio frequency source that is tunable pulse-to-pulse.

Abstract: A technique for disrupting the operation of a target containing nonlinear electronic devices generally includes generating a high frequency signal; generating a low frequency signal; modulating the high frequency signal with the low frequency signal; and emitting the modulated high frequency signal at the target.
