摘　　要：为了提高超声速反舰导弹针对远程舰空导弹的突防效果,将大空域变轨弹道改进为大空域螺旋机动弹道。鉴于降高段是遭遇远程舰空导弹拦截的阶段,将降高段改进为螺旋机动降高弹道。为了完成螺旋机动降高弹道,而且保证降高段后平稳地过渡到低空巡航段,提出了一种带螺旋机动的变结构制导律。最后,进行了大空域螺旋机动弹道仿真以及反舰导弹与远程舰空导弹的攻防对抗仿真。仿真结果表明,反舰导弹采用大空域螺旋机动弹道比以前采用的大空域变轨弹道的突防概率提高了90.7%。The large-airspace varying trajectory is modified to large-airspace spiral maneuver trajectory, in order to improve supersonic anti-warship missile penetration effect against enemy long-distance ship-to-air missile. For the missile＇ s descending phase can suffer interception of long-distance ship-to-air missile, the descending phase is modified to spiral maneuver descending trajectory. In order to accomplish this trajectory and to ensure smoothly transfer to low altitude cruise phase after descending phase, a variable structure guidance law with spiral maneuver is proposed. Finally, the simulation of large-airspace spiral maneuver trajectory is performed, and the attack-defense counterwork simulation between anti-warship missile and long-distance ship-to-air missile is also performed. The simulation results show that the pene- tration probability of anti-warship missile with large-airspace spiral maneuver trajectory increases 90.7% than that with former large-airspace varying trajectory.
