摘要
分析了随机误差 (非统计独立的 )对环形阵旁瓣之影响。分别考虑了振幅误差和相位误差两种情形。证明了随机误差可引起旁瓣电平的升高。对于独立的随机误差之情形 。
The effects of statistically dependent random errors on the sidelobe for ring array are analyzed. The amplitude errors and the phase errors are considered, respectively. It is shown that the random errors cause a rise in the sidelobe level. The simple formulas can also be obtained for the case of independent random errors.
