摘要
讨论了海洋船舶交变电场衰减的基本特征.根据海洋对不同频率电场信号的穿透深度不一样的原理,分析推导了电场引信点火动作的判决依据.引信设计时选择不同的频率信号进行处理,使用电场模量门限、电场上升斜率、不同频率电场上升斜率比及其组合等参数可以简便地控制电场引信,使电场引信具有良好的动作区域性.
The characters of the alternating electric fields emitted from ships are discussed in this paper. The proposal that the electromagnetic penetration depth scale can be used to control the localization of electric field fuse is brought forward. For various frequencies of electromagnetic wave in the seawater, the penetration depth is different. Getting electric field signature by various sampling frequencies, the fuse can compute action zone and make the firing decision simple. The firing criteria of electric field fuse are derived. The fuse can precisely localize the target by these principles such as electric field intensity modulus, rate\|of\|rise, slope ratio\|of\|rise and so on.
