摘要
针对天线相位误差对干涉仪测向的影响问题,分析了不同天线布阵的情况下,天线相位误差对干涉仪测向所产生的影响,计算天线阵列中不同天线阵元的影响因子,并根据影响因子改进天线布阵方式。研究及仿真结果表明,相同基线配置情况下,根据影响因子改进天线布阵的方法有效,可提升解模糊概率,为工程中优化天线布阵提供参考。
Aiming at the influence of antenna phase error for interferometer direction finder,the influence of antenna phase error on interferometer direction finder under the different antenna embattle is analyzed,the influ‑ence factor of the antenna array element is calculated,and according to the influence factor the way of antenna em‑battle is improved.The study and simulation show that different antenna embattle produces different resolving cor‑rect probability when the baseline is same.The results can offer consult for antenna embattle in the engineering ap‑plication.
