摘　　要：研究了空中运动目标在飞行过程中的起电、放电机理和带电特性．通过理论分析和仿真计算,研究 了对于被动式地面静电探测系统,将空中目标的电场近似地作为静电场进行探测和将空中带电目标近似为点 目标的条件．结果表明,对于被动式地面静电探测系统而言,探测距离在10km范围以内,可将目标的电场 当作静电场进行测量:当空中目标与探测器距离大于目标尺寸3～6倍以上时,可将目标视为点目标．提供 了被动式地面静电探测系统的应用前提．The charging process, discharge principle and the charging characteristics of various aerial moving targets are analyzed. Based on theoretical analysis and simulation, the conditions of regarding the target electric field as an electrostatic field to measure and approximating the charged target to a point target of the passive ground electrostatic detection system are analyzed. The results indicates that the target electric field can be measured as an electrostatic field when detection distance is less than 10 km. It can be regarded as a point target when the distance between it and the detector is greater than 3-6 times target size; the application precondition of the system is provided.
