摘要
现有应答器测试的执行标准缺少对标准参考环磁场分布特性的约束检查,且通用的功率采集测试方法收敛迭代次数众多,场一致性测试存在误差大、效率低的问题。本文通过计算环形天线的磁场有限元模型,提出了用于检验标准参考环的磁场分布模型,并基于该模型的功率估计对应答器磁场一致性的测试方案进行优化。经验证,该模型符合实际的磁场分布特性,优化测试方案可以有效提高效率。
The existing execution standards for balise test lack constraint checks on the magnetic field distribution characteristics of the standard reference loop,and the common power acquisition testing methods have numerous convergence iterations,resulting in large errors and low efficiency in field consistency test.This thesis proposes a magnetic field distribution model for testing the standard reference ring by calculating the finite element model of the magnetic field of the circular antenna.Based on this model,the power estimation corresponds to the optimization of the testing scheme for the magnetic field conformity of the balise.After verification,the model conforms to the actual magnetic field distribution characteristics,and optimization can effectively improve test efficiency.
