摘要
针对幅相误差是制约声纳基阵性能的重要因素,建立存在幅相误差的均匀线列阵模型,进而提出统计计算与计算机仿真相结合的方法。该方法通过计算线列阵方向性函数的统计特性,分析具有幅相误差、基元失效时均匀线列阵对基阵指标的影响。仿真证明理论分析是正确的。
Amplitude-Phase errors are important factors that restrict the performance of Sonar array. This paper establishes the model of uniform linear array （ULA） with amplitude-phase errors, and puts forward the method of statistical numeration combining with computer simulation. This method analyzes the effect on the performance of ULA with Amplitude-Phase Errors and element failure through calculating the statistical character of the radiation pattern of ULA. The analysis of theory is true through simulation proving.
