Abstract: The system and method for an additively manufactured radome for a cavity backed notch comprising at least one lattice structure wherein the antenna works over any 4:1 bandwidth, from VHF to mmW. In some cases, the radome lattice has a density that changes with distance from the antenna. In some cases multiple antennas are used for direction finding. The radome may be additively manufactured from glass-loaded polymer or other materials having a low dielectric constant. In some cases, the radome has a dielectric contract that approaches that of air.

Abstract: A digital signal processor is designed to channelize an input signal, and includes a channelizer circuit and a plurality of tuning modules. The channelizer circuit is designed to receive an input signal having a first bandwidth and to channelize the input signal into a first set of channels each having a bandwidth smaller than the first bandwidth as a first output signal and to channelize the input signal into a second set of channels having a bandwidth smaller than the first bandwidth as a second output signal. The plurality of tuning modules are designed to receive one or more channels from the first output signal or the second output signal and to further downsample the one or more channels to a user-defined bandwidth at a user-defined center frequency. Each of the plurality of tuning modules include a plurality of FIR filter blocks and a memory having a plurality of FIR filter coefficients.

Abstract: The present system estimates target motion with nonzero acceleration (including maneuvering uncertainty) using angle only (AO) measurements. The present approach employs a mixed coordinate system framework by combining modified spherical coordinate (MSC) system and Reference Cartesian Coordinate (RCC) system to keep accurate information flowing from one frame to the other while eliminating the numerical sensitivity of the angle measurements to the TSE vector. This integrated coordinate systems framework is achieved due to the state vector information of two frames (RCC and MSC) is effectively preserved between processing cycles and state vector transformation steps. The AO TSE architecture and processing schemes are applicable to a wide class of passive sensors. The mixed coordinate system provides robust real-time slant range estimation in a bootstrap fashion, thus turning passive AO measurements into equivalent active sensor measurements with built-in recursive range information but with greatly improved TSE accuracy.

Abstract: The system and method for a metal meta-material embedded with a phase change material to form an optically induced phase change material. A metal doped polymer domain within the optically induced phase change material provides electric-field enhancement at the interface with a semiconductor domain and provides a thermal heat sink, to provide rapid thermal dissipation away from the semiconductor domain during the optical process.

Abstract: A navigation system for a swarm of guided projectiles, such as cruise missiles, having three or more projectiles launched at a target is provided. The projectiles can be in secure communication with one another and can operate as a single swarm using a fusion of angle of arrival and time difference of arrival of a detected signal to direct the projectiles to a point of impact on a target that is offset from an emitter generating the detected signal. The projectiles can further use knowledge of their relative position to maintain and/or adjust their flight path and/or speed to maintain their course to the point of impact in areas of GPS denial or unavailability.

Abstract: A guided projectile including a precision guidance munition assembly utilizes at least one maneuver envelope to optimally control movement of at least one canard to steer the guided projectile during flight. The maneuver envelopes optimize movements of the at least one canard that effectuate movement in either the range direction or the cross-range direction, or both. The maneuver envelope enables optimal timing such that maneuvering in one direction does not come at the expense of maneuver authority in the other direction.

Abstract: An antenna receiver has antenna elements that are arranged in an array and spaced apart from each other at a distance greater than one-half wavelength of the highest operating frequency of a signal that is to be detected by the antenna receiver. The antenna receiver has geolocation logic that uses the interelement phase difference measurements to obtain a location of the signal source. The change in the inter-element phase differences enables the elements to be spaced apart at great distances, which is beneficial for the physical construction of the platform, as the elements may be easily placed at convenient locations for conformal aerodynamic properties.

Abstract: A method and apparatus for calculating and accounting for non-uniformity of pixels within an infrared (IR) focal plane sensor utilizing an infrared light emitting diode (IR LED) to wash out environmental infrared light is provided. The IR LED may back propagate through an optical path of an IR sensor to illuminate pixels on a focal plane array, thereby providing data by which the non-uniformity offsets may be calculated and removed for normal operation of the IR sensor.
