摘要
作为电磁仿真模型有效性评估的核心内容,仿真结果可信度的定量评估可以消除主观目测评估的不确定性和不稳定性,为仿真模型的修正及改进提供指导。为此论文针对点对点比较法、平滑比较法、加权比较法以及电磁仿真评估领域极为重要的FSV方法,分析了以上方法的原理和评估过程,并基于已知的仿真和测量数据进行了方法间的对比分析:发现除FSV方法外,虽然其他方法可以对不同数据的可信度情况做出正确判断,但其分析结果的数值差异并不能完全反映数据差异的程度,而FSV方法利用自然语言描述仿真结果的可信度,不仅可以较为全面地反映数据差异,同时其参数均是基于电磁仿真这一背景进行校准和设置,因此具有良好的专业适用性。
As core content of the effectiveness evaluation for the electromagnetic simulation model,the quantitative evaluation of the simulation results credibility can eliminate the uncertainty and instability of the subjective visual evaluation,and provide guid⁃ance for the correction and improvement of the simulation model.For the point-to-point comparison method,smooth comparison method,weighted comparison method and the extremely important FSV method in the field of electromagnetic simulation evalua⁃tion,the paper analyzes the principle and evaluation process of the above methods,and conducts inter-method comparisons based on known simulation and measurement data.It is found that in addition to the FSV method,although other methods can make cor⁃rect judgments on the credibility of different data,the numerical difference of the analysis results doesn't fully reflect the degree of data difference,and the FSV method uses natural language to describe the simulation results credibility,not only can reflect the da⁃ta differences more comprehensively,but also the parameters are calibrated and set based on the background of electromagnetic sim⁃ulation,so it has good professional applicability。
