摘要
分析了智能天线阵列的工作原理,在智能天线实验平台上对阵列误差的校正算法进行了实验验证。通过与方位无关的校正矩阵校正之后,各阵元通道的复增益趋于一致,波达方向(DOA)估计精度也在误差允许范围之内。结果表明,这种阵列误差校正方法是行之有效的。
This paper analyzed the working principle of smart antenna array,and tested in the experimental platform of the smart antenna to carry on the confirmation to the array error calibration algorithm.Through correction by the calibration matrix which has nothing to do with the position,complex gain of each array element channel tends to consistency;estimation accuracy of DOA is also within the scope of allowable error.The results show that this method is effective for error correction of array.
