    摘要： A multi-function radio frequency (MFRF) module integrates command guidance, active and semi-active terminal guidance (and possibly passive) and fuzing sensors for gun-launched munitions into a single assembly. The MFRF module can be incorporated into a variety of different gun-launched munitions to execute missions currently performed by guided missiles. The MFRF module is programmable during munition activation to select the guidance mode, active or semi-active, and a primary fuze mode, proximity or height of burst.

    摘要： A sensor for a missile seeker includes a primary, concave, reflector that is reflective to RF waves and to another kind of waves, but that includes a transmissive region, through which RF waves can pass. A secondary, convex, reflector is reflective to RF waves but transmissive, and not reflective, to the other kind of waves, and is arranged facing the primary reflector to further reflect RF waves reflected by the primary reflector through the transmissive region of the primary reflector. An RF detector is arranged on the opposite side of the primary reflector from the secondary reflector and arranged to detect the RF waves reflected by the secondary reflector through the transmissive region of the primary reflector. A second detector, for detecting the other kind of waves, is arranged on the opposite side of the secondary reflector from the primary reflector and is arranged to detect the other kind of waves after they are reflected by the primary reflector and transmitted through the secondary reflector.

    摘要： 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. Alternatively, inexpensive low-quality inertial sensors establish preregistration, deriving a homography matrix. When contrast in the object direction is inadequate, dual sensors yield accurate virtual imaging with an object centroid superposed into background.
