摘要

摘要: 为了克服正交磁环天线结构误差角造成的测向角度(测角)误差较大的问题，该文提出一种结构上改进的三磁环测向天线设计方案。阐述了两两呈60°夹角磁环嵌套结构的三磁环天线的测向原理，建立了三磁环天线测角误差关于结构误差角的仿真模型。仿真分析表明，在相同结构误差角的条件下，相比正交磁环天线，三磁环天线测角误差最大值理论上能够降低50%。低频(f<200 kHz)情况下的对比实验结果表明，相比于正交磁环天线，三磁环天线测角误差最大值降低65%，测角误差总体优化约50%，实验与仿真结果符合较好。

Abstract: In order to overcome the large directional angle error caused by the structure error angle of the orthogonal magnetic loop antenna, a three-magnetic loop directional antenna design scheme is proposed. The principle of the direction finding of the three-magnetic loop antenna is described, and the simulation model of the directional angle error with respect to the structure error angle of the three-magnetic loop antenna is established. The simulation analysis shows that under the same structural error angle condition, compared with the orthogonal magnetic loop antenna, the maximum directional angle error of the three magnetic loop antenna can theoretically be reduced by 50%. The comparative experiment results under the low frequency (f<200 kHz) situation show that compared with orthogonal magnetic loop antennas, the maximum directional angle error of the three magnetic loop antenna is reduced by 65%, and the overall directional angle error is optimized by approximately 50%, the experimental results are in good agreement with the simulation results.
