摘　　要：单个地面探测系统对空目标探测的误差精度的研究涉及到探测所产生三维误差矢量的模以及方向角的分布情况.基于数理统计学中正态分布随机变量的检验方法,检验了对空目标监视所产生的三维误差矢量的方向角以及模的分布,利用所得到的结果进行仿真和精度几何稀释GDOP分析,得到GDOP的值由仿真前的0.47减小到仿真后的0.38.该方法所得到结果在对空目标监视的模拟仿真、情报优化、数据融合以及作战运筹等领域将起到参考作用.The study of detection error precision for single ground radar system used for air target detection gets involved in the distribution of 3D error vector magnitudes and their direction angles.Based on chi square test method of normally distributed random variables in mathematical statistics,this paper examines the distribution of 3D error vector direction angles and magnitudes,makes simulative analysis of GDOP using the previous results and the obtained GDOP value drops to 0.38 after simulation while it is 0.47 before simulation.The results achieved by using this approach can be as a reference for simulation of air target surveillance,intelligence optimization,and date fusion as well as the fields of battle operation,etc.
