摘要
摘要:用于雷电测向的正交磁环天线(OMLA)的测量精度要求不断提高，导致天线自身结构加工误差引起的测角误差(AME)进一步加大。该文对天线自身结构加工误差与测角误差的关系建立理论模型，通过引入补偿系数和等效结构误差角度，提出一种对正交磁环天线测角误差的矫正方法。通过实验对比3组正交磁环天线，对其常规测向结果和矫正测向结果的测角误差进行对比分析，实验表明矫正后测角误差比常规测角误差降低约50%。因此该矫正方法在同等硬件条件下，可以很好地提升正交磁环天线的雷电测向精度。

Abstract:The measurement accuracy for lightning direction finding by the Orthogonal Magnetic Loop Antenna (OMLA) is continuously improved, which results in the Angle Measurement Error (AME) caused by the OMLA machining error increasing. A theoretical model is established for the relationship between the machining error and AME of OMLA. With the compensation coefficient and equivalent non-orthogonal angle error, a AME correction method for OMLA is proposed. The AME of the conventional measurement way and the corrected measurement way are compared through three groups of data experimentally. The experimental results show that the AME by the corrected measurement way is significantly reduced by about 50%. Therefore, this correction method can help the OMLA with the same hardware condition to obtain higher measurement accuracy for lightning direction finding.
