摘要
分析了相位干涉仪测向系统中阵元在三维方向均存在位置误差对测向性能的影响,推导出阵元位置误差存在时测向误差公式;仿真了特定天线阵在不同平面度条件下测向误差分布;利用阵元位置修正改善了测向精度。为天线阵装配、测向误差校正等提供了技术参考。
In the phase interferometer direction finding system, the influence of position error in the three-di- mensional direction on the direction finding performance is given , the formulas of direction finding error with the array position error are derived, the distribution of direction finding error of the specific array is simulated under the condition of different flatness, and the array position correction is used to improve the accuracy of direction finding. It provides technical reference for the antenna array ~ssembly, direction finding error.
