    • A system (34) for determining deviations in the state of motion of a projectile (10) from its intended state includes a comparison module (38) that receives the outputs S of a sensor array (36). The comparison module (38) converts the sensor outputs to a measurement vector Z.sub.m and computes the deviation of this measurement vector from an intended measurement vector Z.sub.0 received from a control system. The comparison module (38) then determines the difference E.sub.Z between this measured deviation and the deviation predicted by a Kalman filter (44, 46). In generating the measurement vector Z.sub.m from the outputs of the sensor array (36), the comparison module (38) "de-spins" the array outputs in accordance with the output of a phase reference (42), whose purpose is to indicate the phase with respect to gravity of the spin of the projectile (10) about its longitudinal axis. The Kalman filter's state-deviation estimator (46) weights the vector output of the comparison module (36) and adds it to the output of the Kalman filter's state-deviation predictor (44) to provide an updated state-deviation estimation E.sub.X (t:t), which the state-deviation predictor (44) then uses as a basis for its next cycle. The output of the comparison module (38) constitutes a measure of the performance of the state-deviation predictor (44) and is used as a correction factor for the phase reference (42) so that the system acts as a phase-locked loop to lock the phase reference (42) onto the projectile spin without the need for an external sensor to determine the direction of gravity.
    • 用于确定弹丸(10)的运动状态与其预期状态的偏差的系统(34)包括:接收传感器阵列(36)的输出S的比较模块(38)。 比较模块(38)将传感器输出转换为测量矢量Zm,并计算该测量矢量与从控制系统接收到的预期测量矢量Z0的偏差。 比较模块(38)然后确定该测量的偏差与由卡尔曼滤波器(44,46)预测的偏差之间的差EZ。 在从传感器阵列(36)的输出生成测量矢量Zm时,比较模块(38)根据相位基准(42)的输出“去”旋转阵列输出,其目的是指示 相对于射弹(10)的旋转的重力围绕其纵向轴线。 卡尔曼滤波器的状态偏差估计器(46)对比较模块(36)的矢量输出进行加权,并将其加到卡尔曼滤波器的状态偏差预测器(44)的输出端,以提供更新的状态偏差估计EX(t: t),状态偏差预测器(44)然后用作其下一个周期的基础。 比较模块(38)的输出构成了状态偏差预测器(44)的性能的量度,并被用作相位参考(42)的校正因子,使得系统充当锁相环 将相位基准(42)锁定在抛射体旋转上,而不需要外部传感器来确定重力方向。

    • Techniques and architecture are disclosed for performing alignment harmonization of a collection of electro-optical and/or gimbaled componentry that is to operate within a common coordinate frame. In some cases, the techniques and architecture can provide a cost- and time-efficient approach to achieving alignment harmonization that is compatible, for example, with field-test and/or operational environments. In some instances, the techniques and architecture can be used in concert with error calibration techniques to further improve the accuracy of the alignment harmonization. The techniques and architecture can be utilized with a wide range of components (e.g., sensors, armaments, targeting systems, weapons systems, countermeasure systems, navigational systems, surveillance systems, etc.) on a wide variety of platforms. Numerous configurations and variations will be apparent in light of this disclosure.

    • Techniques for missile countermeasures are disclosed. The techniques can be employed to rapidly detect a missile system location and aim a countermeasure set at the missile system goniometer, and capture the goniometer with a high radiant intensity countermeasure beam before the goniometer narrows its field of view (FOV). Capturing the goniometer before a narrowing of its FOV allows for wider area protection. The techniques can be embodied in an area-protection hit-avoidance system for a rapid Semi-Active Command to Line of Sight Anti-Tank Guided Missile (SACLOS ATGM) countermeasure wherein a SACLOS ATGM launch is rapidly detected and a countermeasure is aimed at the launch site so that the missile is diverted before the ATGM system FOV is narrowed. This early diversion or decoying of the missile guidance set allows the countermeasure to protect a greater area and to engage multiple threats in less time than traditional countermeasures.
