摘　　要：对于采用平面圆阵布设的被动式地面静电探测系统,根据误差理论分析结果研究了其阵列参数,即探测阵列半径、探测阵列的阵元个数以及探测器电极尺寸对探测阵列目标定位精度的影响;探讨了被动式地面静电探测系统平面圆阵阵列参数的优化方法.利用均匀设计法对阵列参数进行优化,其回归和方差分析的结果表明:在一定条件下,探测阵列半径为300 m,探测阵列圆周上的阵元个数为44,探测器电极半径为1.4 m时,系统定位精度最高.Round array parameters of passive ground electrostatic detection systems comprise the detection round array radius, detector number of the array and the electrode size. Influence of the round array parameters to the precision of location are studied first with the help of error theory. Then array parameters optimization of the round array is discussed in detail. The array parameters of the round array are optimized using the uniform design method, the regression analysis and variance analysis results indicate that in certain condition, highest precision of location of the detection system can be obtained when the detection array radius is 300 m, the number of the detectors arranged on the round array circumference is 44, and the detection electrode radius is 1.4 m.
