摘　　要：根据某水下目标的抗水下爆炸试验数据,阐明了选用加速度峰值和速度峰值作为测量指标的原因,然后通过相关分析法研究这些指标之间的相关性,利用正交旋转法的因子分析得到影响目标毁伤的公共因子,并通过分析正交旋转因子载荷阵选择出特征指标,讨论特征指标与毁伤模式之间的关系,最后分别利用公共因子数据和特征指标数据进行目标毁伤判别,两组数据的判别结果与实验结果基本一致,证明了特征指标选择的合理性。In the experiment of a underwater target subjected to underwater acceleration and peak velocity as measurement indexes was illustrated, and the studied through relevant analyses. The common factors affecting the target damage explosion, the reason of choosing peak correlation between these indexes was were obtained by using the orthogonal rotation of factor analysis, and the feature indexes were selected through factor loading matrix of orthogonal rotation, and the relationship between feature indexes and damage patterns was discussed. The rationality of the choice of feature indexes was verified according to the agreement between the damage detection results by experiments and by using the common factors and feature indexes suggested.
