Abstract: The design of detecting electrodes in a capacitance fuze is a critically important factor that determines its sensitivity. Capacitance fuzes base their operation on the laws of static electric fields. The projectile, the electrodes，and the target are here taken as a 3-conductor .system， upon which the physical model and mathematical model are built up， permitting one to calculate and analyze the conductor system using the charge simula?tion method. Electrodes and projectiles having different shapes and sizes were then put under test. Synthesis of the results of theoretical analysis and tests results in a design principle for detecting electrodes. With this principle the design of a detecting electrode for use on a 152mm projectile is finally given as an example.
