摘　　要：空中运动目标带电量高且难以去除,这为静电探测系统提供了理论依据。介绍了一种电压微分式的静电探测系统,利用目标在探测器位置的场强变化得到了感应电压公式,然后对其微分后得到了变化的电流。通过仿真验证了该公式的正确性和实用性,并据此设计了相应的探测电路,通过实验验证了该探测系统的可行性。Moving targets in the sky have a high quantity of electric charges, which are hard to be removed. This provides a theoretical basis for the electrostatic detecting system. In this paper, a voltage differential electrostatic detection system is introduced, the induced voltage formula is deduced by the variation of field strength around the detectors. After that, the changing current is obtained by differentiating the induced voltage. The validity and practicality of the formula were verified by the computer simulation, and then the corresponding detection circuit was designed accordingly. Finally, the feasibility of the detection system was confirmed by the experiments.
