本文讨论了基元信号的振幅及相位起伏对AR方法阵处理器性能的影响,着重研究了均方倒声束图案及定向误差,注意到了参考基元以及基元信号起伏之间相关性的作用。结果表明,起伏一般使均方声束图案展宽以致畸变。相位起伏产生定向误差,其标准方差正比于起伏的标准方差并与基阵基元数有关,起伏之间的相关性对定向误差有重要作用。 In this paper, we discuss the influence of amplitude and phase fluctuation of the primitive signal on the performance of the AR method array processor. We focus on the mean square inverse beam pattern and the directional error, and note the correlation between the reference primitive and the fluctuation of the primitive signal . The results show that the fluctuation generally broadens the mean square beam pattern to distortion. The undulation of the phase produces orientation error, whose standard deviation is proportional to the standard deviation of the undulations and is related to the number of elements in the array. The correlation between undulations plays an important role in the directional errors.
