Abstract: A zero knowledge communications protocol is provided that can unconditionally secure communications sent through a communications network by encrypting all messages, continuously sending noise messages through the network, and routing all network activity through an anonymity network. This combination of components prevent an eavesdropper on the network from garnering any information about when a communication is sent, the contents and statistics of a communication, the sender, or the intended recipient of the communication.

Abstract: The present disclosure relates generally to a network system having multiple users, multiple inputs, and multiple outputs to transmit data from a data source through a link to a data sink. One example of a Multi-user multiple input multiple output (MU-MIMO) system relates to the use of primary transceivers and secondary transceivers in respective networks that effectuate data transmission. The primary transceivers are coupled with a data source and broadcast or transmit the data source signal to a plurality of secondary transceivers in a local area network. The signal is then transmitted over a long link to another set of secondary transceivers that then pass the signal to another primary transceiver. This another primary transceiver is coupled with the data sink to effectuate signal transmission to the data sink. The data is synchronized in manner that requires minimal processing and does not require closed loop phase control.

Abstract: A platform with an auto-router takes into account non-navigation data, such as IR image sensor data or other non-navigation data to develop a route for a platform. The non-navigation data may be obtained from existing non-navigation sensors carried by the platform. The non-navigation data is fed to an auto-router that takes into account the non-navigation data to generate or dynamically alter a route for the platform.

Abstract: An endfire antenna structure is disclosed that is for use on aerodynamic systems. The antenna structure includes a first layer of patterned metal, a second layer of patterned metal, and a stack of material layers that includes the first layer of patterned metal and the second layer of patterned metal. The first layer of patterned metal includes a plurality of parallel slots etched through the metal. The second layer of patterned metal includes a tapered radio frequency (RF) feedline having a narrow end coupled to an input/output (I/O) antenna connection. The second layer of patterned metal is aligned over the first layer of patterned metal such that the tapered RF feedline has a length that extends across the plurality of parallel slots. The stack of material layers is flexible such that the stack of material layers is configured to wrap at least partially around the fuselage of an aerodynamic system.

Abstract: A monocone antenna with an impedance matching section that may allow a reduction in physical size of the cone while maintaining similar performance as a standard monocone antenna. Alternatively, the present disclosure may provide a monocone antenna with an impedance matching section that may allow operation at a lower frequency while maintaining the same physical size as a standard monocone antenna. Further, the present disclosure may provide a monocone antenna with an impedance matching section that may allow a reduction in physical size and operation at a lower frequency relative to a standard monocone antenna.

Abstract: Techniques are provided for tomographic imaging with sub-beam resolution and spectral enhancement. A system implementing the techniques according to an embodiment includes a target structure comprising one or more selected materials nanopatterned on a first surface of the target structure in a selected arrangement. The system also includes a primary particle beam source to provide a particle beam incident on an area of the first surface of the target structure, the area encompassing one or more of the nanopatterned materials, such that the materials generate characteristic X-rays in response to the primary beam. The system further includes a spectral energy detector (SED) to perform individual photon counting and spectral analysis of the characteristic X-rays and estimate attenuation properties of the imaged sample. The sample is positioned both adjacent to a second surface of the target structure, opposite the first surface, and between the target structure and the SED.

Abstract: A heat dissipation structure is disclosed that is especially well-suited for use on aerodynamic systems. The heat dissipation structure is formed within a metallic body that surrounds the heat-generating electronics. The heat dissipation structure is designed to both dissipate the generated heat and also to isolate RF cross-talk between the one or more transmitters and receivers. The heat dissipation structure includes a plurality of ring structures that extend around at least a portion of a body that houses the one or more heat-generating electrical components. The plurality of ring structures may be recessed into the body, and a first spacing between a first adjacent pair of ring structures of the plurality of ring structures is different from a second spacing between a second adjacent pair of ring structures of the plurality of ring structures.

Abstract: Techniques are provided for phase coherent frequency synthesis. An embodiment includes a first phase accumulator to accumulate a frequency control word (FCW) at a clocked rate to produce a first digital phase signal representing phase data corresponding to phase points on a first sinusoidal waveform. The embodiment also includes a second phase accumulator to produce an incrementing reference count at the clocked rate and multiply it by the FCW to produce a second digital phase signal representing phase data corresponding to phase points on a second sinusoidal waveform. The multiplication is performed in response to change in the FCW. The embodiment further includes a multiplexer to select between the first and second digital phase signals based on completion of the multiplication. The embodiment also includes a phase-to-amplitude converter to generate digital amplitude data corresponding to the phase points on a sinusoidal waveform associated with the selected digital phase signal.

Abstract: A system and method for a bistatic coherent LIDAR system with lasers locked to a reference. Utilizing atomic absorption lines to lock the frequency for the bistatic system provides an absolute reference, as each of the lasers in the bistatic system would have the same frequency to within the linewidth of the frequency reference. Each laser may also be additionally locked to an optical cavity for increased frequency stability. Not only does such a system provide essentially an infinite aperture, it also reduces laser power requirements because the detector platforms could be much closer to the target than the platform that contains the laser.
