无人攻击机垂直命中目标的末制导律研究

综合考虑电视指令制导无人攻击机的作战过程，将其末制导律设定为满足落角约束的目标跟踪问题，设计了一种基于自动驾驶仪末制导律，该方法消除了自动驾驶仪动态因素和重力等因素的影响；并通过以平行接近法作为辅助导引法来克服追踪法的缺陷；新的末制导律加自适应卡尔曼滤波，使得无人攻击机不仅可以对固定目标实施攻击也可以对低速移动目标实施攻击，且能保持无人攻击机垂直命中目标，提高作战效能。

Study on the Terminal Guidance Law of Hitting the Target Vertically for UCAV

Considering the attack process of the television guidance UCAV, taking a terminal guidance law of UCAV as a problem of tracking the target at meeting the impact attitude angle restriction, the law based on autopilot was designed, which eliminates the influences of dynamic factor of autopilot and gravity factor on hitting the target. The parallel approach acted as the assistant guidance was used for designing the law to conquer the defect of the pursuit guidance. The law with Kalman filtering makes UCAV attack either immobile target or mobile one at low speed and hit the target perpendicularly to improve the operational efficiency.
