舰空导弹超视距拦截制导律设计与指令解算

针对舰舰协同制导舰空导弹超视距拦截低空飞行目标问题,在初制导段,设计了一种指数型制导律,保证导弹由发射姿态平滑快速地转至装定角;在中末制导段,应用最优控制理论,设计了对目标机动和视线角速率量测噪声具有强鲁棒性的最优制导律;考虑地球曲率,以经纬度位置为基准,通过一系列坐标变换,将目标信息变换到发射坐标系下,建立了制导律所需各种信号指令的解算模型.仿真结果验证了协同制导指令解算模型的正确性和制导律的可行性与鲁棒性.

Design of Guidance Law for Beyond-visual-range Interception of Ship-Air Missile and Instruction Solution

For the case of ship-air missile intercepting the low target beyond visual range by ship-ship coordination,an exponential guidance law was designed in the initial segment to ensure that the missile turned the launch angle to the setting angle smoothly and fast.An optimal guidance law was designed by applying the optimal control theory in the midcourse and terminal guidance segments,which has strong robustness to target maneuver and noise of the velocity of LOS angle.By a series of the coordinate transformat...
