目前靶场主要采用扇形靶试验方法来测定弹丸的杀伤半径,其原理就是弹丸垂直放置,按不同距离分别设置6个圆心角为60°的靶,通过破片命中靶板的统计结果,来计算弹丸的杀伤半径。扇形靶试验结果原理上等同于弹丸综合威力试验时轴向90°的状态,其定义可以用杀伤概率来表示,即一定距离处一个人形靶上命中一块破片的概率为0.632时,该距离为杀伤半径。杀伤半径的结果可以通过分析弹丸综合威力试验数据进行计算,而不必要再次开展扇形靶试验。

Sectorial target test method is mainly used to measure killing radius, the principle is that the projectile is placed vertically, 6 targets with the central angle of 60° are placed according to different distance, the projectile's killing radius can be calculated through statistical result of fragments hitting target. Sector target test result is theoretically equivalent to axially 90° state in projectile synthetic power test, the distance is the killing radius when the kill probability is 0.632. Lethal radius results can be obtained by analyzing the projectile synthetic power test data with no need to conduct sector target test again.
