Abstract

The method for estimating statistical characteristics of radiation field, amplitude-phase distribution, and correlation function of phase errors of arbitrary aperture antennas is presented. It is convenient for analyzing the statistics of antenna arrays with axial symmetry. The main mean and fluctuation characteristics within the direct external problem of statistical antenna theory are determined on the example of cylindrical circular antenna array. The estimation of the mean power radiation pattern, main lobe direction fluctuation of array, and comparison with the known results are carried out. We show that according to the estimated statistical characteristics, circular cylindrical arrays occupy an intermediate position between linear and circular ones.

小相位误差条件下轴对称天线阵统计特性的估计

摘要

提出了估计任意孔径天线辐射场统计特性、幅相分布和相位误差相关函数的方法。便于分析轴对称天线阵的统计量。统计天线理论直接外在问题中的主要均值和涨落特征以圆柱圆形天线阵列为例确定。对平均功率辐射方向图、阵列主瓣方向波动进行了估计，并与已知结果进行了比较。我们表明，根据估计的统计特性，圆柱阵列占据线性阵列和圆形阵列之间的中间位置。
