反舰导弹在末制导跟踪阶段受到质心干扰后，雷达导引头跟踪误差增大、跟踪方向被诱骗，致使导弹命中概率下降。惯导信息具有天然的抗干扰潜力，综合利用惯导与反舰导弹雷达导引头信息能有效对抗质心干扰。在分析质心干扰原理的基础上，建立了质心干扰检测模型，舰艇、假目标、质心运动模型，以及反舰导弹跟踪模型，并构建了抗干扰仿真试验系统，通过系统仿真分析了舰艇机动方式、假目标施放时刻弹舰距离、导引头比例导引系数、目标回波信噪比等因素对导弹命中舰艇概率的影响。

When anti-ship missiles are effected by centroid jamming during the terminal guidance phase, the tracking error of radar seeker will increase, the tracking direction will be decoyed, which may lead to a serious reduction in missile hit probability. The inertial navigation information has the inherent potential of anti-jamming,and synthetically applying the information of inertial guid- ance and anti-ship missile radar seeker can effectively confront the centroid jamming. Based on ana- lyzing the principle of centroid jamming,this paper sets up the centroid jamming detection model, the ship, false target, cetroid motion model, as well as anti-ship missile tracking model, and con- structs the anti-jamming simulation test system, through system simulation, analyzes the influence of several factors such as ship maneuvering mode, the distance between missile and ship when false target is released,guidance coefficient seeker ratio and signal-to-noise of target echo on missile hit ship probability.
