Abstract: An apparatus for dampening at least one optical instrument on a military platform. The apparatus includes a plate adapted to hold at least one optical instrument. The apparatus also includes at least one dampening assembly having a first end operably engaged with the plate and an opposing second end operably engaged with a platform. The at least one dampening assembly is also adapted to reduce the movement of the plate and optical device from a ballistic event created by a ballistic device on the platform.

Abstract: A tightly coupled dipole array is an egg-crate configuration defined by a plurality of electrically connected antenna unit cells. At least one of the unit cells utilizes a short or conductive element that shorts the common mode resonance. Shorting the common mode resonance in an intentional manner removes instances of the common mode resonance. To achieve the shorting of the common mode resonance, a conductive element is connected with one of the dipole arms and connected to the outer conductor of the feed or a ground plane. This creates a grounding loop that pushes the resonance out of the band of interest.

Abstract: The system for an antenna assembly for use on unmanned underwater vehicles (UUV). The antennas are low-cost, lightweight, single-use, and have a small form factor amenable to use on a micro-UUV. A central post and pivotally attached arms form an antenna (e.g., a monopole) that is lifted via an aerial, kite, or the like, when deployed from the UUV to extend the line of site of the antenna several meters above the surface of the water. In some cases, the antenna may be used on a number of UUVs in a swarm formation.

Abstract: Methods and structures are disclosed for providing autonomous control of an underwater vehicle using a state machine. A controller is used onboard the underwater vehicle and includes a state machine having a plurality of operating states. Each of the plurality of operating states includes one or both of entrance criteria and exit criteria. The controller is configured to transition from executing a first operating state of the plurality of operating states to executing a second operating state of the plurality of operating states in response to the exit criteria of the first operating state and the entrance criteria of the second operating state both being met. The plurality of operating states includes a first portion of operating states associated with a first task, a second portion of operating states associated with a second task, and a third portion of operating states associated with both the first and second tasks.

Abstract: A Mid-Wave Infrared (MWIR) objective and relay lens system has an F# of 3.33 and angular field of view of 15.28°. It is deployed, with a focal plane and scanning system, on airborne platforms for wide area motion imagery. It is corrected for monochromatic and chromatic aberrations over of 3.3 to 5.1 micrometers. Effective focal length is 20 inches, and the overall length is 40.70 inches. The lens has, from object to image, two groups of optical elements with a cold shield/aperture stop 6 inches from the image plane. Group 1 acts as an objective lens with a positive power and three elements, Group 2 acts as a relay lens has a positive power and four elements. The lens is made of Germanium and Silicon. It used in a scanning system in a pre-objective configuration where the fast scan mirror is located in front of the lens system.

Abstract: Techniques and architecture are disclosed for a method for making a custom circuit comprising forming a common wafer template, selecting at least two elements of the common wafer template to be chosen elements, and adding at least one metal layer to interconnect the chosen elements to form a circuit. The common wafer template includes a plurality of transistors, a plurality of resistors, a plurality of capacitors, and a plurality of bond pads. Final circuit customization of the common wafer template is accomplished by adding at least one metal layer that forms interconnects to passive and active elements in the template in order to complete the circuit.

Abstract: Local detail enhancement (LDE) is an imagery contrast enhancement method applied to visible and uncooled long wave imagery. It enhances local spatial detail through the use of a median based high/band pass filter. The generated detail channel is blended with a histogram-equalized version of the image, creating an image that contains both local detail as well as retaining some amount of global intensity. Retaining global intensity coherency allows for easier target acquisition when compared to fully local forms of contrast enhancement.

Abstract: The present disclosure is a system comprising at least three electronically steered antennas arranged so that there is a baseline difference of a predetermined amount of wavelength between the centers of the antennas, typically configured as an obtuse or scalene triangle, where the distance between each antenna on an array is selected to provide the required accuracy and precision, the array having a timing circuit to ensure that the beam of each antenna is steered to the same azimuthal and elevation coordinates in space simultaneously. This enables the three electronically steered antennas to operate as an interferometer to determine a bearing to a target to ultimately determine the location thereof. The electronically steered antennas enable the system to be mounted on a platform in a small package that was previously difficult for traditional interferometers.

Abstract: An underwater imaging system is carried by a submersible platform to capture images that are processed into three-dimensional images stitched together to create a 3D dimensional video at video rate speeds that are transmitted to a control unit above the surface of the water. The imaging system utilizes a high speed image sensor or camera to capture sequential gated images that are synced via a gating module to two sequential laser beam pulses. The laser beam pulses illuminate an object in each gated image. When the object is within a gate overlap region, the two images may be processed using 3D imaging techniques to generate a 3D representation of the object in the overlap region of the two gates.

Abstract: A wideband chaotic waveform that is rateless in that it may be modulated at virtually any rate and has a minimum of features introduced into the waveform. Further, the waveform provided may be operated below a signal to noise ratio wall to further enhance the LPD and LPE aspects, thereof. Additionally, the present disclosure may provide a mix of coherent and non-coherent processing techniques applied to signal samples to efficiently achieve coarse synchronization with a waveform that is faster, more efficient and more accurate than using time domain signal correlators alone.
