中文摘要：

在综合孔径可见度函数模型的基础上，推导了天线位置误差对可见度函数的影响。以一种交错Y形阵列为例对天线位置误差进行了分类研究，并针对其无法单独被校正的特性，采用了一种需利用外部辅助源的整体校正方法对其进行了校正仿真。仿真结果表明了这种方法的有效性。

英文摘要：

Based on the visibility function expression of synthetic aperture radiometer, the impact of antenna position errors on visibility function is obtained. The antenna position errors are classified on a staggered Y-array for an instance. A calibration method using external reference is adopted due to that the errors can not be calibrated individually. The simulation results demonstrate the effectiveness of the calibration method.
