论文摘要
在本文中,我们提出了一种光束形成方法,用于校准光圈阵列的模拟链的方向无关增益。通过使用阵列的其他天线将每个天线的输出电压交叉相互交叉相关,从而获得增益估计值。当波束形成的重量等于平均交叉相关的功率时,与Stefcal算法达成了关系。一个示例说明了几个点源和256个元素数组的方法。
In this paper, we propose a beamforming method for the calibration of the direction-independent gain of the analog chains of aperture arrays. The gain estimates are obtained by cross-correlating the output voltage of each antenna with a voltage beamformed using the other antennas of the array. When the beamforming weights are equal to the average cross-correlated power, a relation is drawn with the StEFCal algorithm. An example illustrates this approach for few point sources and a 256-element array.
