用概率统计方法分析随机幅度与相位误差对米波圆阵雷达方向图的副瓣电平、波束宽度和波束指向等指标的影响，分析结果表明：相位误差对性能指标影响要大于幅度误差，尤其是在波束指向及副瓣角度上。幅度误差通常主要影响副瓣电平。文中给出了计算机仿真并验证了分析结果。

The radom range and phase error in probability statistical method for the influence of petal level,beam width and beam directional etc.of the direction picture of the metre wave round battle array are analysed.The analysis result shows: phase error will be more big than range as function index affects error,on the directional and petal angle in beam especially.Range error usually affect the petal level mainly.The computer simulation gives the analysis resuit in this paper.
