为增强反舰导弹的机动突防能力,根据反舰导弹与舰空导弹的对抗过程,构建了反舰导弹螺旋机动对舰空导弹武器系统的突防模型。通过研究脱靶量的提取方法,给出了舰空导弹对反舰导弹的遭遇拦截判据,对反舰导弹螺旋机动突防概率进行仿真计算。仿真结果表明,通过优化组合弹道可以选择合适的螺旋机动方案,对于反舰导弹突防能力的提高效果显著。 In order to enhance the ability of anti-ship missiles to defend against maneuver, according to the confrontation between anti-ship missiles and ship-to-air missiles, an anti-ship missile penetration model for ship-to-air missile weapon system was constructed. By researching the extraction method of miss distance, the intercepting criterion of ship-to-ship missile encountering anti-ship missile was given, and the probability of penetration of anti-ship missile was calculated. The simulation results show that the optimal helical maneuver scheme can be selected by optimizing the combined trajectory, and the effect of improving the penetration capability of the anti-ship missile is significant.
