摘　　要：阵列误差的校正是智能天线技术实用化的关键所在。对各种阵列误差进行了深入分析并建立了数学模型。阵列误差可以用一个误差矩阵来表征,通过对误差矩阵的估计,能够恢复理想的阵列流型。实验结果表明,这种阵列误差校正方法能够有效减小各阵元通道之间的差异,改善了系统的性能。Array error calibration is the key problem for the application of smart antenna technology. All kinds of array errors are analyzed and their mathematical models are also established. Array error can be represented as an error matrix. The nominal array manifold can be restored by the estimation of the error matrix. The results show that this method can effectively reduce the difference of the antenna element patterns, and greatly improve the performance of system.
