    Abstract: An interferometry system and method thereof detects movements of the surface of a body of water in response to acoustic waves generated from a sub-surface source interacting with the surface. Movements of the surface of the body of water are viewed over multiple interferometric images that can be pieced together to generate an interferometric movie or video. The interferometric movie or video depicts the movement of the acoustic wave propagating through the viewing area. Once the movement of the acoustic wave propagating through the viewing area is known, then back propagation techniques are employed to determine or triangulate the location of the sub-surface source that generated the acoustic wave.

    Abstract: System and methods for generating super resolution images from geospatial images having any number of bands. A super resolution model, which uses deep convolution neural networks (DCNNs), is trained using individual image bands, a large crop size or tile size of 512×512 pixels, and a de-noise algorithm. Applying one or more algorithms to maintain the original color of the image bands improves the quality metrics of the super resolution images as measured by PSNR (peak signal-to-noise ratio) and SSIM (structural similarity index measure) of super resolution images. Further applying one or more algorithms to remove border effects introduced during the disclosed process reduces and/or eliminates seam lines between tiles and enhances the overall accuracy of the super resolution images.

    Abstract: Techniques are provided for guiding a projectile. A methodology implementing the techniques according to an embodiment includes generating a roll command based on a roll angle obtained from a steering map that causes a change in range and cross range of the projectile that results in a ground motion closest to a desired ground motion. The method also includes calculating a remaining maximum maneuver distance for the projectile, over a time period extending from the current time of flight to the end of flight. The calculation is based on integration a series of maximum maneuvers, obtained from the steering map, at time intervals within the time period. The method further includes generating a lift command for the projectile based on: distance between the target location and an impact point prediction (IPP) calculated at the current time of flight; an error estimate of the IPP; and the remaining maximum maneuver distance.

    Abstract: A method of growing large GaAs or GaP IR window slabs by HVPE, and in embodiments by LP-HVPE, includes obtaining a plurality of thin, single crystal, epitaxial-quality GaAs or GaP wafers, cleaving the wafers into tiles having ultra-flat, atomically smooth, substantially perpendicular edges, and then butting the tiles together to form an HVPE substrate larger than 4 inches for GaP, and larger than 8 inches or even 12 inches for GaAs. Subsequent HVPE growth causes the individual tiles to fuse by optical bonding into a large “tiled” single crystal wafer, while any defects nucleated at the tile boundaries are healed, causing the tiles to merge with themselves and with the slab with no physical boundaries, and no degradation in optical quality. A dopant such as Si can be added to the epitaxial gases during the final HVPE growth stage to produce EMI shielded GaAs windows.

    Abstract: Various countermeasure dispensing systems (or CMDSs) and method of use are described herein. CMDS may include a dispenser assembly operably engaged with a platform where at least one electrical connection provides electrical communication between the dispenser assembly and a sequencer. CMDS may also include a magazine assembly operably engaged with the dispenser assembly, wherein the magazine assembly comprises a magazine configured to hold at least two countermeasure expendables. CMDS may also include a breechplate assembly operably engaged with the magazine assembly and adapted to dispense the at least two countermeasure expendables. CMDS may also include at least one magazine identification switch (MIS) operably engaged with the magazine assembly and the breechplate assembly. CMDS may also include that the at least one MIS is configured to enable the sequencer and the breechplate assembly to selectively dispense at least one countermeasure expendable from the at least two countermeasure expendables.

    Abstract: The system and method generates a pulse or a signal that is transmitted between a central processing unit or processor and an Ethernet integrated circuit card to program a trigger generator in the IC. The pulse is effectively a 1PPS signal that is provided to the IC, which may be in the form a field programmable gate array to enable timing synchronization. The trigger in the IC may also generates an interrupt to the processor so a driver in the CPU is instructed to set the next trigger. For the trigger to be accurately controlled, the control routine is implemented in the driver existing in kernel space rather than user space. A routine or protocol periodically polls the interrupt to determine when the trigger must be reset.
