Diagonal position error is a very important property to assess the antenna-array's electricity performance,and it affects the believability of hardware-in-the-loop simulation directly.This paper discusses the effect of center departure between the tested device's electricity axes and the array radicalization on diagonal position error.Some validations were done through testing.%角位置误差是衡量天线阵列电性能好坏的一个重要指标,它会直接影响半实物仿真结果的置信度.研究了被试设备电轴中心与阵列辐射中心不重合对角位置误差造成的影响,并通过试验的方法加以验证.
