针对飞行器寻的制导问题，提出了一种既能控制攻击时间又能控制攻击角度的制导律，可用于反舰导弹的有效齐射攻击或无人机的协同任务。拟议的法律可以引导车辆在规定的撞击角度下，在指定的撞击时间到达目标。它包括一个反馈回路和一个附加控制命令，第一个控制命令用于实现零脱靶量的期望冲击角，第二个控制命令用于控制冲击时间。数值仿真结果表明，该方法具有较高的撞角和碰撞时间精度。
This paper proposes a new guidance law to control both impact time and impact angle for a flight vehicle's homing problem, which can be applied for an efficient salvo attack of antiship missiles or a cooperative mission of unmanned aerial vehicles (UAVs). The proposed law can lead vehicles to home on a target at a designated impact time with a prescribed impact angle. It comprises a feedback loop and an additional control command, the first to achieve the desired impact angle with zero miss distance, and the second to control the impact time. Numerical simulations demonstrate the performance of the proposed law in the accuracy of impact angle and impact time
