Abstract: The system and method for super resolution processing at long standoff distances in real-time. The system collects a series of image frames and estimated the sift, rotation, and zoom parameters between each of the image frames. A matrix is generated and then an inversion is applied to the matrix to produce a super resolution image of an area of interest while mitigating the effect of any “bad” pixels on image quality. In some cases, the area of interest in user-defined and in some cases image chips are provided by tracking software. A fast steering mirror can be used to steer and/or dither the focal plane array.

Abstract: A multi-axis rotary actuator includes a payload support configured to be rotatable about a first axis, a disk surrounding at least a portion of the payload support, and an elevation wheel rotatably coupled to the payload support. The disk is configured to be rotatable about the first axis. The elevation wheel is configured to be in contact with the disk and to be rotatable about a second axis perpendicular to the first axis. The actuator can include a mirror or other device coupled to the elevation wheel. The mirror or other device is configured to be rotatable about the first axis and the second axis as the payload support and the elevation wheel rotate about the first axis and the second axis, respectively.

Abstract: A system for transmitting optical communications includes a transmitter, a receiver, and a processor. The transmitter includes a light source driven by a driver circuit under control of a micro-controller to transmit an optical signal. The optical signal can be encoded by a frequency-modulated encoding scheme. The receiver includes an optical lens, an imaging sensor configured to receive the optical signal and a memory. The processor is configured to extract one or more frequencies from the optical signal for only those pixels that are changing and thus decreases an overall data rate for the system and allows for larger pixel arrays, thereby decreasing the accuracy requirements of any pointing hardware and to reconstruct a waveform for each of the extracted frequencies.

Abstract: Techniques are provided for fabricating a low profile antenna that operates with increased efficiency. An antenna implementing the techniques according to an embodiment includes a first arm comprising a first spiral portion and a first rectilinear portion, and a second arm comprising a second spiral portion and a second rectilinear portion. The second spiral portion is concentric with the first spiral portion. The antenna further includes an insulator to separate the arms. The insulator and the arms are planar surfaces disposed within a rectangular region. The first rectilinear portion is adjacent to a first and second side of the perimeter of the rectangular region, and the second rectilinear portion is adjacent to a third and fourth side of the perimeter of the region. The antenna is fabricated as a printed circuit board which is mounted on the fuselage of an aircraft, which serves as a ground plane for the antenna.

Abstract: An emitter ID ambiguity reduction system includes a Mission Data File Ambiguity Resolution matrix that contains both a) the INTEL-based emitter parameters data necessary to break emitter-by-emitter ambiguities, and b) the action(s) the Electronic Warfare (EW) system is to take to collect that data. Control software is triggered via either external command or per Mission Data File information (such as that contained in the Ambiguity Resolution Matrix). The emitter ID ambiguity reduction system includes Data collection hardware and firmware and Data Analysis OFP software algorithm(s).

Abstract: A guidance system for a projectile having a mid-body. The guidance system having a mid-body semi-active laser seeker. The seeker has an objective lens assembly and a sensor array that reads laser energy and transmits data to determine the direction of the laser energy. A glint management unit is connected to mid-body in such a manner that glint laser energy is prevented from passing to the objective lens assembly and sensor array so as to enhance determination of the location of the target.

Abstract: A system and method for using coherent aggregated bandwidth over multiple transmissions for improved performance of precision guidance and positioning and of object tracking systems. Angular offset (Az/El) estimations are strongly impacted by interference between direct and (comparable amplitude) ground-reflected signals. In rough ground situations, there could be many ground reflected signals. Bandwidth aggregation as used herein achieves sharper range sidelobes and smaller magnitude multipath interference terms resulting in increasingly accurate interferometric results.

Abstract: The system and method for combining two optical assemblies into the same volume, particularly when the field of view of the two assemblies are different, so that the overall volume and size, weight and power (SWaP) for the system is reduced. This also allows both subsystems (e.g., narrow field of view (NFOV) and wide field of view (WFOV) to use a single aperture and the same external protective window, reducing overall cost for a system of co-located dissimilar optical systems in a single aperture.

Abstract: The system and method for EO/IR and RF sensor fusion and tracking using a dual extended Kalman filter (EKF) system provides a dynamic mixing scheme leveraging the strength of each individual sensor to adaptively combine both sensors' measurements and dynamically mix them based on the actual relative geometries between the sensors and objects of interest. In some cases the objects are adversarial targets and other times they are assets.
