舰载激光引偏系统的安全引偏距离可以采用冲击因子破坏标准计算，但传统的冲击因子破坏标准在计算安全引偏距离时存在一些不足。引入舰船的尺度、外形和排水量等参数对破坏标准中冲击因子的计算方法进行了改进，使之具有更加广泛的适用范围，然后在改进的冲击因子破坏标准基础上，计算了多种激光制导武器相对于不同类型舰船的安全引偏距离，分析了相关因素对安全引偏距离的影响，对舰载激光引偏干扰系统引偏距离的选择具有一定的参考意义。%The ship-damage standard of impulsive factor for underwater explosion was used to calculate the safe distance of a ship-based laser decoy jamming system.The modification for the calculation method of impulsive factor in the standard expanded the scope of application of the standard through introducing parameters of size,external form and water discharge of warships.Then,based on the improved standard,the safe distances of three types of warships with different laser guidance weapons were calculated and the effects of the corresponding factors on the safe distance were analyzed. The results provided a reference for selection of safe distance of a ship-based laser decoy jamming system.
