中文摘要：

针对反舰导弹制导中的箔条质心干扰对抗场景，首先阐述了导弹在跟踪箔条云团和目标舰的合成质心时会产生切割效应，接着对切割效应进行了分析。通过建立数学模型，设置典型参数场景，对在切割效应下的质心干扰进行了仿真，并对结果进行了分析。其结果表明，切割效应会对干扰效果产生影响。其结论对于抗箔条质心干扰技术的研究具有一定的参考意义。

英文摘要：

Aiming at chaff centroid jamming confrontation in anti-ship missile guidance, the effect of incising would be generated when the missile tracked the centre of chaff cloud and ship. A precise beam incision impact model was derived. Based on the model and reasonable scene assumption, centroid jamming in incision effect was simulated. Simulation results were analyzed, which indicated the effect of incising would influence the result of jamming. These results had kind of refer- ence value in the judgment of centroid jamming validity and the coming research on chaff centroid jamming countermeasure.
