鱼雷电磁引信作用距离模糊分析及抑制方法

从鱼雷电磁引信收发线圈垂直配置方法基本原理出发,分别分析了位于鱼雷轴线和偏离鱼雷轴线的双接收线圈产生作用距离模糊的原理。对于第一种情况,提出了对双路线圈输出信号进行取模处理的方法,消除了作用距离模糊；对于第二种情况,提出了通过增加对称位置的接收线圈,并对对称位置线圈输出信号求平均后,再进行取模处理,消除了作用距离模糊。仿真结果表明,该方法可有效消除作用距离模糊,提高电磁引信作用距离。

Analysis and suppressing method for the operating range ambiguity of torpedo electromagnetic fuze

Starting from the basic principle of the vertical configuration of the receiving and transmitting coils of torpedo electromagnetic fuze, the ambiguity of operating range caused by the double receiving coils located on the torpedo axis and deviating from the torpedo axis were analyzed respectively. For the first case, the modulo operation of the double receiving coils was proposed to eliminate the ambiguity of the operating distance; for the second case, a pair of coils was appended to the symmetrical position and the output signal of the symmetrical position coil was averaged, then the modulo operation was taken to eliminate the ambiguity of the operating range. Simulation results show that the method can effectively eliminate the ambiguity of the operating range and improve the operating range of the electromagnetic fuze.
