摘要
提出了一种有源阵面大量单元失效情况下的局部校准方法,根据概率理论和最小二乘法对单元幅相误差进行了最佳估计,考虑了实际工程中的幅相调整误差,理论分析和仿真计算结果均表明了这种方法的正确性和有效性。
This paper proposes a partial calibration scheme for active phased antenna arrays with most failure elements. By considering the amplitude and phase adjustment error in practical engineering, the amplitude and phase error of element is optimally estimated on the basis of probability theory and least squares method. Theoretics analysis and simulation computation results testify the correctness and validity of this calibration scheme.
