天线阵通道不一致及阵元间互耦的有源校正法

Calibration with Signal Source for Channel Uncertainties and Sensor Mutual Coupling of Antenna Array

在超分辨测向领域模型误差往往会导致系统性能的急剧下降 ,因此必须进行有效的校正。首先研究了借助于单个辅助信号源来校正模型误差的方法 ,对它的原理进行了详细的推导和分析 。

In superresolution direction-finding, model errors often degrade system performance, so effective calibration is needed. With the help of one assistant signal source, the paper discusses a calibration approach, whose principle is derived and analyzed in detail. Finally, some computer simualtion results demonstrate that this approach is feasible.
