毫米波制导攻击型无人机攻击机动目标制导律研究

对于攻击机动目标的攻击型无人机而言，其攻击精度受目标机动性的直接影响。为了提高攻击型无人机毫米波末制导系统的制导精度，在目标机动加速度模型的基础上，利用毫米波主动雷达导引头测得的无人机与目标相对距离和相对速度信息，研究了目标机动加速度的估计算法，并根据最小能量控制的指标提出了一种具有较强工程可实现性的攻击机动目标的最优制导律。仿真结果证明了该导引规律具有优良的特性。

Guidance Law Disquisition for UAV to Attack Maneuvering Targets Basing on Millimeter-wave Guidance

For an attacking UAV which is used to attack maneuvering targets, its attack precision is influenced firsthand by the maneuverability of the targets. For the purpose of improving guidance accuracy of the millimeterwave terminal guidance system, the information of relative distance and relative velocity between the UAV and the target which is measured by the seeker of millimeter-wave initiative radar are utilized. An algorithm for estimating the maneuvering acceleration of the target is investigated An optimal guidance law for attacking maneuvering targets basing on minimal expense of energy, which can be actualized easily in engineering, is derived. The excellent characteristics of the guidance law are proved by the emulation results.
