反舰导弹末端机动的突防效果研究

利用共轭系统和拉氏变换技术,重点研究了反舰导弹的螺旋机动和摆式机动的突防效果。螺旋机动和摆式机动的加速度可以用纵向和航向平面内的加速度分量来表示。在平面内分析机动加速度引起的稳态脱靶量得到了简单的脱靶量解析解。利用该解析解,分析了机动持续时间对稳态脱靶量的影响。将纵向和航向平面内的稳态脱靶量综合起来得到了螺旋机动或者摆式机动所引起的稳态脱靶量。仿真结果表明这两种非平面机动方式比平面机动方式具有更好的突防效果。

Reasearch on the Penetration Effect of Terminal Maneuver for Anti-ship Missiles

The penetration effect of spiral maneuver and cycloid maneuver has been mainly researched for antiship missiles using the adjoint system and Laplace transform technique.The accelerations of spiral maneuver and cycloid maneuver can be expressed by their components in the pitch plane and the yaw plane.The simple solution of the miss distance has been obtained by analyzing the steadystate miss distance resulted from the maneuver acceleration in the plane.The effect of the maneuver continuing time on the steadystate miss distance is researched using the above solution.Synthesizing the steadystate miss distances of the pitch plane and the yaw plane gives the steadystate miss distance caused by the spiral maneuver or the cycloid maneuver.The simulation results show that the two forms of nonplanar maneuvers have better penetration effect than the forms of planar maneuvers.
