A digital beam is formed by coherently combining the plurality of digital signals within the FPGA.

    Abstract: An electronic analog memory system includes at least one analog programmable delay module configured to receive an input radio frequency pulse. The analog programmable delay module generates a time delayed output signal in response to applying at least one time delay to the input radio frequency pulse. A switching module is configured to selectively deliver the time delayed output signal to an output of the electronic analog memory system. The electronic analog memory system further includes an activity detector module configured to determine the amplitude of the input radio frequency pulse. The activity detector module also controls the switching module to deliver the time delayed output signal to the output in response to the at least one amplitude exceeding an amplitude threshold.

    Abstract: A low-power digital logic architecture exhibits the same logic and voltage level behavior as standard digital logic. A logic switch and a pair of unidirectional switches are used to control the direction of charge flow in a switched-inductor capacitor (SLC) circuit, allowing the inductor to pull charge back-and-forth from one side of the load capacitor to the other to both switch the logical state at the top of the capacitor and to recycle and store the charge in the capacitor itself.

    Abstract: Embodiments of a system and method for providing efficient wideband inverse channelization for direct digital synthesizer based jamming techniques are generally described herein. In some embodiments, metadata associated with a technique for generating a waveform, such as frequency, phase and amplitude parameters, is received. Data select signals and data input are generated based on the received metadata. In-phase and quadrature signals are produced at an output of a first de-multiplexer and a second de-multiplexer, respectively, based on the data select signals and the data input. Frequency modulated signals generated by direct digital synthesizers may be combined in a channel using a separate, distinct channel combiner.
