摘　　要：针对静电探测体制下目标及干扰的静电特性研究不足的问题,提出了静电探测目标及箔条云联合建模方法,研究了典型目标及箔条云的表面静电电荷分布、空间静电场分布,分析了不同箔条云形状、带电总量、相对目标位置距离等特征因素对目标静电电荷分布、静电场的影响,揭示了探测器与目标处于不同相对位置时目标的静电带电特征规律,获取了探测器静电感应场的变化特性。结果表明:目标尖端部位静电荷积累密集;目标静电特性受箔条云带电总量影响,呈线性变化规律;探测器感应电流呈正弦分布,交会速度越快电流幅度越大、频率越高。研究成果可用于支撑静电探测器目标及箔条干扰特性研究。Address the problem of insufficient research on characteristics of targets with chaff cloud interference in electrostatic detection system,the federated modeling approach of targets with chaff clouds is proposed.The distribution of electrostatic charge on the surface of typical target with chaff clouds and the electrostatic field in space are studied.The influence factors on the distribution are analyzed including the shape and the electrostatic charges of the chaff clouds,the distance between the typical target and chaff clouds,et al.The variety of induced charge has been revealed when the detector in a different position relative to the target.The properties of induced current of the detector are obtained.The results show that the electrostatic charges gather at the tips of the target.The detector charges are linearly affected by the electrostatic charges of chaff clouds.The induced current of the detector is the sine function form.Its amplitude is stronger and its frequency becomes larger when the rendezvous speed is faster.The research results can support the devise of the electrostatic detector considering target with chaff clouds.
