静电引信目标电场建模

Target Electric Field Modeling of Electrostatic Fuze

研究了飞机上安装的静电放电针空间电场分布。静电放电针是飞机上释放静电的装置,由于静电放电针在释放静电时具有特有的空间电场,因此为了使静电引信能够利用这些信息来探测目标,需要掌握静电放电针的工作机理和空间电场分布情况。在一定的约束条件下,建立了静电放电针空间电场分布的数学模型,并进行了理论的分析,得到了静电放电针空间电场电位和电场强度的公式。仿真结果表明,所建立的数学模型基本符合静电放电针空间电场分布的特征。

A research on the space electric field distribution of the electrostatic discharge needle installed on the aircraft was undertaken.Electrostatic discharge needle is a device on aircrafts which can discharge electrostatic.When the electrostatic discharge needle discharges electrostatic,there is a unique space electric field around it.In order to use the information to detect the target,research on the mechanism and the space electric field distribution of the electrostatic discharge needle is needed to conduct.Under the certain restrictive conditions,the space electric field distribution model of the electrostatic discharge needle was established and analyzed theoretically.Finally the formulas of the electric scalar potential and the electric field intensity vector were obtained.The simulation results show that the mathematical model basically meets the distribution characteristics of space electric field of the electrostatic discharge needle.
