【摘要】 静电隔墙探测系统中,目标在大地介质中产生的感应电荷会对探测系统造成影响.为了提高目标探测精度,必须研究地面感应电场对静电探测系统的影响.根据两无穷大垂直放置的导电平面系统中点源目标静电场分布和镜像法,对地面静电隔墙探测系统中点源像电荷的分布及电量表达式进行了推导;建立了地面静电隔墙探测系统的数学模型,并进行仿真分析,得出地面感应电场对探测系统的影响不大,并且可以得出一定条件下的最远探测距离.更多还原

【Abstract】 To improve the detection accuracy to the target,the influence about ground induction electrostatic field to the system of the electrostatic detection should be studied.Basing on the electric field distribution of the point charge in the two infinite upright planes and the image method,the distribution and electricity quantity of the image charge of the goal in the system of the electrostatic detection through the obstacle on the ground are analysed.The mathematics model of the passive electrostatic detection system on the ground through the obstacle is established.By the simulation it can be given that the influence about the ground induction electric field to the detection system is small and the farthest detection distance depending on a condition is gained.更多还原
