摘　　要：正交静电探测阵列由6个呈正交分布、独立工作的静电探测器组成。对于同一带电目标,探测器空间分布的差异会使每个探测器的输出信号在相位上发生变化,形成与目标速度信息、方位信息相关的信号序列。结合探测器探测方程,得到了基于感应信号零点检测的空中目标测速定向方程。仿真及实验的结果表明,该方法具有很高的测速定向精度,测量误差在5%以内,可应用于对低空带电目标的地面预警及静电引信对静电目标的定向测速。The orthogonal electrostatic detection array is composed of six electrostatic electrodes,they are fixed in pairs and work independently.For a charged object,the spatial distribution differentiation among different electrodes will cause variation of the phase information on the output signals of different electrodes,based on which the information related to the velocity and direction of the moving object can be obtained.Combining with the detection equation of the electrostatic electrode,the determination equation of the motion velocity and direction of the air target based on the cross-zero detection of the induced signals is obtained.Simulation and experiment results prove that this method has the advantage of high accuracies of velocity and detection determination,the measurement error can be controlled within 5％ ; the method can be applied in the ground early-warning the charged low level air targets and the directional velocity measurement of electrostatic fuze to a electrostatic target.
