摘　　要：研究2A12铝弹丸超高速碰撞2A12铝靶板产生的电磁场对通信电路的干扰.实验中采用盘式磁线圈对超高速碰撞产生的电磁场进行测量,获得了碰撞速度为5.93 km/s下不同的空间位置处磁感应强度以及与上弹道方向平行的不同放置位置处通信电路的受干扰情况.实验结果表明:超高速碰撞产生的电磁场会使通信电路受到严重的干扰,电磁场对通信电路的干扰幅值达到了1 V.An experimental system was constructed to test the electromagnetic interference on communication circuit when 2A12 aluminum projectile with hypervelocity impacts 2A12 aluminum target. The disc magnetic coil was used to test the electromagnetic field generated by impact. The degree of interference on communication circuits, which was placed at different points parallel to the direction of upper trajectory, was experimentally obtained when the impact velocity was 5.93 km/s. The result indicates that the electromagnetic field generated by hypervelocity impact interferes seriously to the communication circuits. The amplitude of interference voltage could reach to 1 V.
