    • In the present invention, an aircraft control device computes the trajectories of a plurality of formation-flying aircraft using a calculation method; e.g., direct collocation with nonlinear programming (DCNLP), in which the optimal solution is obtained by discretizing continuous variables. Trajectory-indicating nodes are computed and set by plugging discretized aircraft control variables into an aircraft motion equation or by using another method. Using discretization to address aircraft trajectories reduces complexity and allows the trajectories to computed more rapidly than with computations involving chronologically contiguous aircraft trajectories. The aircraft control device determines the optimal trajectory, among trajectories that comply with constraints corresponding to the role of the aircraft, on the basis of an assessment value obtained by an objective function corresponding with the role. Accordingly, the aircraft control device is capable of performing computations more rapidly on more suitable trajectories corresponding with the role of the aircraft.
    • 在本发明中,飞行器控制装置使用计算方法来计算多个编队飞行器的轨迹, 例如直接与非线性规划搭配(DCNLP),其中最优解通过离散化连续变量而获得。 轨迹指示节点通过将离散化的飞行器控制变量插入飞机运动方程或通过使用另一种方法来计算和设置。 使用离散化来解决飞机轨迹降低了复杂性,并且允许轨迹的计算比涉及按时间顺序连续的飞机轨迹的计算更快。 飞行器控制装置基于由与该角色相对应的目标函数获得的评估值来确定符合与飞机的角色相对应的约束的轨迹之中的最优轨迹。 因此,飞机控制装置能够更加快速地在与飞机的作用对应的更合适的轨迹上执行计算。

    • The invention relates to a system for protection of a vehicle (2) against a possible threat (4) approaching the vehicle. The system comprises a sensor (6) that detects the possible threat, a control unit (8) that evaluate the possible treat and transmit processed information, a counter-measure apparatus (2), and a launcher (10) that receives a launching signal from the control unit for launching the counter-measure apparatus towards (D1) the threat when the treat is confirmed. The counter-measure apparatus (2) comprises a guiding unit (12) by which the counter-measure apparatus (2) is guided towards the threat (4) based on the processed information of the threat that is continuously received via the control unit (8), during acceleration of the counter-measure apparatus (2). The counter-measure apparatus further comprises a counter-measure element (14,18) that is launched in a direction (D2) against the threat (4) by means (16) for releasing and activating the counter-measure element (14,18), when the counter- measure apparatus (2) has reached within the vicinity of the threat (4), such that the counter-measure element (14,18) can defeat the threat (4). The invention also relates to an apparatus and a method for protection of a vehicle against a possible threat approaching the vehicle.

    • An improved missile guidance system is provided which automatically compensates for jitter motion of the optical sight of a video tracker. The invention is adapted to receive video data input from an infrared detector or conventional camera (12). The invention includes circuits for filtering, gating, and digitalizing the incoming data as well as a formatter for directing successive frames into memory. Two memories (36, 40) are provided; the contents of which are sampled by matching logic (42) as the second memory is being loaded. The matching logic (42) thereby compares one frame of data to another at plurality of positions and provides a signal to an address latch (46) when the best match is obtained. The format circuitry (32) provides the position information to the address latch where it is stored for further processing. The output of the address latch is filtered to eliminate any signals representative of intentional tracking motion. The filtered output thus provides the jitter correction to the missile guidance system (60) where missile guidance signals are compensated by the jitter correction.
