Study on electrode potential of capacitance proximity fuze

Detection mechanism of capacitance proximity fuze is the base of fuze design work. Electric field and circuit methods are used to calculate the potential proportional relationship between the two electrodes. The potential of electrode I is obtained through experiment. Thus we can get the potential of electrode II. Pispce software is used to simulate the whole circuit, and get the simulation result of potential of electrode II. The experiment comes to the conclusions as following: the potential of electrode II decreases when fuze gets close to the target; and the potential proportional relationship between the two electrodes based on the two methods are nearly same; potential of electrode II based on theory and experiment fits the result of simulation.
