了解碎片的散布特性对于精确规划最终阶段以及使用定向破片战斗部（FGW）摧毁目标至关重要。作者进行了实验，以研究具有圆形破片产生面的两种FGW配置中碎片的空间散布情况。在本文中，利用投影角的均值和标准差对碎片的散布进行量化。通过夏皮罗 - 威尔克检验，验证了投影角的散布遵循正态分布。由于边缘效应，周边碎片的散布更高。对于位于大于炸药装药半径0.7倍的径向距离处的碎片，观察到投影角有更急剧的变化。这些观察结果与赫尔德（1988年）对于方形破片产生面的研究结果一致。
Understanding the dispersion characteristics of fragments is essential for precise planning of the end game and the neutralization of targets using directional fragment generator warheads (FGW). The authors have carried out experiments to study the spatial dispersion of the fragments in two configurations of FGWs having a circular shaped fragment generating surface. In this paper, the dispersion of the fragments is quantified using the mean and standard deviation of the projection angle. Using the Shapiro-Wilk test, it is verified that dispersion in the projection angle follows a normal distribution. The dispersion of the peripheral fragments is higher due to edge effects. A steeper variation in projection angles is observed for fragments placed at a radial distance greater than 0.7 times the explosive charge radius. These observations are in agreement with the results of Held (1988) for a square shaped fragment generating surface.
