摘要：The finite element method is first introduced into the design process of detecting electrodes of three electrode capacitance fuze, the mutual capacitance of the fuze and target is calculated by the finite element method, which provides the parameters for simulation circuit and design of detecting electrode. The finite element method pierces the traditional method of designing detecting electrode-design, test and adjustment. The system capacitance can be calculated accurately and the performance can be predicted in the design period of the detecting electrode, which saves a lot of research fee. The capacitances of a mortar shell fuze above ground 2 m and lower are given. After putting the computing data into simulating circuit, the demodulation voltage can be obtained, its changing trend is in agreement with the tested result.

摘要：以静电平衡状态下导体具有的性质为理论依据,建立了两极板主动式静电引信的模型,并对其电场进行了分析,计算得到检测极板上电荷随弹目距离变化的目标特性曲线。设计了相应电路来测量检测极板上电荷的变化率,并介绍了后续信号处理电路的工作原理。得出结论:弹目接近过程中,检测极板上电荷的变化率逐渐增大,即电荷检测电路的输出电压逐渐增大;电路输出电压的分辨率与电极电荷量、极板及目标尺寸、极板间距以及弹目夹角有关,同时与弹目相对速度成正比。该工作对主动式静电引信的设计工作有重要的指导意义。

摘要：Aim To get the theory base of designing FM fuze's jamming signal, its jamming mechanism was studied. Methods A sinusoidal FM fuze was analyzed in time domain and frequency domain and the concept of channel leak was presented. Results It was proved that information channel leak exists in FM fuze because of the nonlinear property of the mixer. The jamming signal was designed based on the channel leak and the jamming mechanism was analyzed in detail. Conclusion This kind of jamming signal can jam the sinusoidal FM fuzes effectively just depending on the jamming signal's feature itself. It's different from the traditional jamming way of simulating echo. Though the sinusoidal FM fuze was just analyzed, the principle is applicable to all FM fuzes. At the same time, it may be used as the reference for FM radar and communication countermeasures.
