摘要
水下弹丸测速常采用感应式线圈靶作为区截装置。以点磁偶极子作为磁化弹丸的物理模型 ,运用电磁学理论 ,导出了弹丸穿越线圈靶时的感应电动势表达式 ,分析了线圈靶半径对区截信号的影响 。
Coil target is usually used to measure velocity of underwater bullet.Magnetic dipole is made as physical model of magnetized bullet.By using electromagnetic theory,the formula of induced electromotive force when bullet flying through the coil target is obtained,and finally the influence of inductive coil target's radius distribution on induced signal is discussed.The result is instructive for measuring underwater bullet.
