Abstract: A correlation and track system identifies whether a Radar warning (RW) Track contains one or more emitters by receiving a set of initial Short and Long Baseline Interferometer (SBI) (LBI) detections; receiving inertial navigational data; receiving subsequent LBI detections; determining whether the LBI detections represent one or multiple emitter(s) by designating an initial SBI conic with a multiple of its one sigma conic Direction Finding (DF) accuracy window as containing the emitter; laying down a set of grid points within the SBI conic window as possible emitters' locations; summing real and imaginary values of a residual phase in the form of a unit vector at each grid point for each LBI update; identifying whether there are one or more emitters in RW track based on whether the magnitude of a peak vector is above or below a defined threshold; and invoking geolocation algorithms based on the vector's magnitude.

Abstract: An all-metal antenna element with integrated common mode rejection realized with an all-metal fabrication and a balanced feed. Further, the present disclosure may provide an all-metal antenna element which may extend the bandwidth of the aperture, allow for simple linear frequency and platform scalability, and may improve the compatibility of arrays to modern digital phased array chains.

Abstract: The present disclosure relates to a chaff dispensing system that is provided on an aircraft. The chaff dispensing system includes a container, a dispensing assembly, a controller, and a volume of chaff material. The container has a first end, a second end, and a chamber that extends between the first and second ends, and the second end defines an ejection port. The dispensing assembly is provided on the aircraft, and the dispensing assembly is operably engaged to the container. The controller is electrically connected to the dispensing assembly. The volume of chaff material is disposed inside the chamber of the container. The volume of chaff material is dispensed by the dispensing assembly operably through the controller in metered volumes of chaff material. In addition, a first volume of chaff material may be metered at a first time and a second volume chaff material may be metered at a second time in which the second volume of chaff material is different than the first volume of chaff material.

Abstract: An infrared imaging system is provided. The system includes a sensor configured to receive light emitted by a scene and at least a portion of scenic flux to generate image data, a light source configured to provide calibrating light to offset at least a portion of the scene flux, the light source positioned such that an output of the light source is at a pupil of the infrared imaging system, and at least one image processing device. The image processing device is configured to receive the image data generated by the infrared sensor, determine at least one change in the scenic flux as received by the infrared sensor, determine if the at least one change in the scenic flux results in a change in pixel response of the infrared sensor that exceeds a response threshold, and if the change in pixel response exceeds a threshold, generate an updated calibration table.

Abstract: The system and method for cooling a laser using a split liquid cooled heat exchanger. The temperature of coolant entering the system is applied to a portion of the system most in need of lower temperatures and a second heat exchanger uses the outflow from the first heat exchanger to cool a remaining portion of the system that has a tolerance for higher temperatures. The laser cooling system is compact, e.g., less than 45 cubic inches and can handle thermal loads of about 800 W.

Abstract: Techniques are provided for vision-based altitude estimation using one or more platform mounted cameras. An embodiment includes generating projected ground imagery of imagery provided by cameras of the platform, the projection based on a hypothesized altitude. The method also includes obtaining reference ground imagery based on the location of the platform, the location based on platform navigation data. The method further includes registering the projected ground imagery to the reference ground imagery and generating a match score associated with the registration. The method further includes selecting the hypothesized altitude as the estimated altitude based on the match score (e.g., if the match score exceeds a threshold value or is maximized over a set of hypothesized altitudes. The method may further include otherwise adjusting the hypothesized altitude and repeating the altitude estimation process based on the adjusted hypothesized altitude to search for an improved estimated altitude based on the match score.

Abstract: The system and method of a steering a moving object using a control plate-based control actuation system on the moving object. The control plate-based control actuation system having a control plate with at least four fin linkages for connecting at least four fins to the control plate; and three actuators configured to move the control plate to produce movement in two or more of the at least four fins. The system produces roll, pitch, and yaw moments for the moving object using three actuators acting on the control plate and thus moving two or more of the at least four fins all with no loss of performance as compared to systems with four actuators.
