  • Patent number: 9476677
    Abstract: A KV-based missile defense system and method of strategic engagement provides performance improvement for both singleton and raid scenarios by launching multiple interceptors that place a follower KV in a trailing position with respect to a lead KV. Knowledge of the target cloud gained by the lead KV is transmitted to the follower KV and incorporated to inform the target selection of the follower KV. The follower KV trails the lead KV with sufficient spacing in time and distance to select a target and maneuver to engage the target pre-acquisition. This also allows the follower KV to receive and incorporate knowledge of target impact by the lead KV. This knowledge may be transmitted back to another follower KV and so forth in a “string” of KVs to inform target selection and down to the ground to inform strategic engagement. Updated non-KV observational data can be uplinked and transmitted forward along the string to the lead KV.

    Abstract: A methodology for initial orbit determination of an object about an astronomical body searches a grid of possible boundary values on the range-to-object over the observation interval to find the grid point and corresponding initial orbit that best fits all of the more than three (N) angles-only observations according to an error metric. The search is conducted by solving a boundary-value problem for different grid points. The state vector is propagated to determine estimated observation directions for the remaining N?2 observations. The grid point (and initial orbit) that best fit all of the observations is selected. For efficiency, the search may start with a broad but coarse initial grid and increase the resolution of the grid as the search converges to a solution.

    Abstract: A rapid anomaly detection approach with corresponding method and system to detect anomalies in scene pixels making up a hyperspectral scene, efficiently, is presented. The approach includes tailoring an approximation of an anomaly score for each scene pixel, individually, based on an “intermediate anomaly score.” The intermediate score is computed using a portion of the terms used to compute the anomaly score. Scene pixels with low intermediate anomaly scores are removed from further processing. The remaining scene pixels are further processed, including computing anomaly scores to detect anomalies in these pixels. Advantageously, examples of the RAND approach process a few terms of all scene pixels, eliminate most scene pixels, and calculate more terms on high anomaly scoring scene pixels as needed.

  • Patent number: 8975564
    Abstract: This invention advances the related state-of-the-art by eliminating the physical EO window used by electro-optical imaging infrared seekers for tactical missiles and high-altitude endo-atmospheric interceptors, widely employed in integrated defense systems. This invention increases the probability of intercepting exo-atmospheric ballistic warheads by exo-atmospheric interceptors, and eliminates the existing altitude “gap” of interception, as well as the geographical limitations posed by the mesospheric Noctilucent Clouds. The problem of protecting an imaging EO sensor from aeroheating is solved in this invention by a special purpose device which is enabled immediately after the nose cone ejection event.

  • Patent number: 8975565
    Abstract: An interceptor is provided with an integrated propulsion and attitude control system (ACS) in which propellant burn forms a common pressure vessel for high-pressure gas. An aft port in the rocket motor directs gas through one or more main nozzles that expel high-velocity gas in a generally axial direction to propel the interceptor. A forward port directs gas through one or more attitude control nozzles that expel high-velocity gas in a generally radial direction to control the attitude of the interceptor. The main nozzle(s) and stabilization fins are fixed, there is no servo control to the main nozzles or fins to affect attitude control. The use of a common pressure vessel enables an integrated propulsion and ACS that can be compact, lightweight and inexpensive.

  • Patent number: 8946606
    Abstract: Apparatus/method estimate LOS rotation, to track, approach, pursue, intercept or avoid objects. Vehicle-fixed imagers approach/recede-from objects, recording image series with background. Computations, from images exclusively, estimate rotation vs. the vehicle, applying the estimate. Preferably, recording/estimating provide proportional navigation; scan mirrors extend strapdown-sensor FOR; applying includes measuring “range rate over range”, exclusively from interimage optical flow, using results to optimize proportional-navigation loop gain; estimating includes evaluating interframe optical flow, preregistering roughly as first approximation, selecting sequence anchor points, and applying a second, finer technique developing output registration that's a coordinate translation, aligning inertial surroundings. The approximation operates optical flow with efficient embedded registration/mapping, applying a homography matrix to nearby imagery.

  • Patent number: 8933382
    Abstract: A missile guidance system is configured to estimate a time to go, the time to go comprising an amount of time until a missile would reach a closest point of approach to a target. The guidance system is also configured to estimate a zero-effort miss distance along a zero-effort miss vector, the zero-effort miss distance comprising a distance by which the missile would miss the target if the missile performs no future maneuvers. The guidance system is also configured to determine a tolerance for the zero-effort miss distance, the tolerance being a function of the time to go. The guidance system is further configured to modify a course of the missile by adjusting an expenditure of propellant such that the estimated zero-effort miss distance in excess of the tolerance is removed from future consideration.
