In order to evaluate the effectiveness of stealth vessel's infrared centroid jamming,based on MATLAB,the influence for effectiveness of jamming is analyzed by some parameters with simulation.Some conclusion are presented with missile undershooting distance as reference.Some parameters may obviously influence the effectiveness of stealth vessel's infrared centroid jamming such as infrared bait's shipboard angle,vessel's infrared radiant intensity,missile incipient distance,missile guidance device visual angle,missile velocity,wind direction,etc.But the proportion guidance modulus of missile and wind velocity has low influence for jamming effectiveness.%针对隐身舰艇红外质心干扰效果评估问题,应用Matlab仿真工具,以导弹脱靶距离为主要参考值,详细仿真分析了多种因素对干扰效果的影响,并得出了以下重要结论:红外诱饵弹发射舷角、舰艇红外辐射强度、导弹离舰艇的初始距离、导弹红外导引头视场张角、导弹速度、风向等参数对隐身舰艇红外质心干扰效果具有明显影响,而导弹比例导引系数、风速对干扰效果影响不大.
