    Abstract: A guidance assembly and method for guiding an ordnance to a target. The assembly can operated in navigation and targeting modes and has an imager/seeker including an objective lens assembly and an imaging sensor array which provide image data for mapping and terminal seeker performance. The imager/seeker is pivotally mounted on the ordnance. An actuator is coupled to the imager/seeker and can be actuated to pivot the imager/seeker relative to a longitudinal axis of the ordnance from a navigation position to a targeting position. A flight control unit communicates with the imager/seeker and the actuator, and has a processor which analyses the image data to provide navigation flight control signals for guiding the ordnance in the navigation mode of operation and determining a target direction via automatic target recognition or aimpoint algorithms for directing the ordnance to the target in the targeting mode of operation.

    Abstract: An RF frequency tuning-in-silicon photoconductive-switch-based high power microwave system including a cradle; a transmission line proximate the cradle; a photosensitive silicon material switch component also proximate the cradle; a laser light source having a varied illumination incidence location on the photosensitive material; and a laser alignment component providing the location of the illumination incidence location on the photosensitive material; whereby the inductance of the switch varies as a function of the incidence location of the illumination on the photosensitive material.

    Abstract: An optical seeker assembly having an optical detector located within the wing or canards of a precision guided munition. The optical seeker provides on-wing processing that generates low bandwidth detection data that can be easily transferred to a primary CPU located within the main body or fuselage of the precision guided munition. The on-wing processing reduces or eliminates the need for optical fibers extending between an optical wedge and an optical detector to reduce the likelihood of optical fibers from impeding in the mechanical deployment of the wing and reduces losses. The reduction or elimination of optical fibers between the optical wedge and the optical detector further enables the optical detection assembly to have a higher pixel ratio or transmitting raw data between the wedge and the detector by sending sampled detection data across a low bandwidth link to a CPU in the main body.

    Abstract: A system and method of verifying hardware that includes software configured to control its operation, the method comprising providing an abstracted version of hardware to be tested; verifying the functionality of the hardware; writing test bench software using physical-layer routines; drafting hybrid verification intellectual property modules, wherein the hybrid verification intellectual property modules comprise both synthesizable and non-synthesizable code and are configured to stimulate the abstracted hardware and to test software anticipated to be used in connection therewith; and creating network-level routines that can be passed to physical-layer routines as part of a hardware verification process.

    Abstract: An F-theta lens provides more than 88 degrees FFOV, F #2.8 or less, length not more than 200 mm, and/or 2.5 μm or better resolution, with color correction from 450 nm to 650 nm. The lens includes three optical groups having positive, negative, and positive optical powers respectively, which can include four, four, and six elements, respectively. Embodiments include an aperture stop in the center of the second optical group. Refractive indices and ray heights are selected to correct for field curvature. Embodiments further include a CMOS detector having pixel pitch of 1.25 microns or less, density of 18 megapixels or more, focal plane diameter of 57.2 mm or more, Nyquist sampling of 400 lines per mm or more and wide pixel field of view of 30° or more. A plurality of CMOS detectors can be arrayed to create a mosaic image.
