红外成像制导导弹分布式协同制导律研究

Aiming at the problem of infrared guided imaging missiles cooperative attack, a novel collaborative detection oriented distributed cooperative guidance law considering the restrict of FOV, consensus of impact time and impact angle was proposed based on the network synchronization principle. Firstly, motion equations including relative distance and FOV were established. With the help of coordinate transformation, the consensus problem of impact time and impact angle was converted into the consensus problem of relative distance and FOV. Secondly, the modified component of pure proportional guidance and tangential acceleration based on the distributed synchronization strategy were derived considering restrict of FOV. Finally, sufficient condition to achieve simultaneous attack was proposed, and the parameter design method was given. The proposed guidance law does not rely on the central node and adapts the non-constant velocity. Besides, it has the advantage of considering restrict of FOV and low communication cost. The proposed guidance law is suited for distributed cooperative guidance for infrared imaging guided missiles.
