中文摘要：
针对独立校准信源波达角未知情况下的阵列位置误差校正问题，提出了一种对信号导向矢量的绝对相位进行最小二乘线性拟合？进而估计出阵元位置误差的算法。并对算法的性能进行了详细分析，推导出位置误差估计的显示表达。该算法在对阵元位置误差进行估计时无需迭代运算，甚至不需要一维搜索，具有较低的运算复杂度。理论分析和仿真结果验证了该算法的有效性。
英文摘要：
A new algorithm for linear array position calibration is presented. In the case of source direction-of-arrival （DoA） is uncertain, by using the least square algorithm, the source DoA is estimated based on the unwrap phase of the steering vector. Then the sensor position error is directly estimated. The performance of array position calibration is also presented. The advantages of this approach are that the accurate source DoA estimates are implemented without iterative operations or the search of a multi-dimensional space under array sensors position is uncertain. The effectiveness of the algorithm is proved by extensive simulation.
