Fidelity Verification Method of Electromagnetic Environment Based on Grey Relational Degree Analysis

提出了一种基于电磁环境逼真度的宏观评估方法,把电磁环境逼真度评估的问题转化为基于灰关联度的图像相似度度量问题,较好地解决了逼真度评估过程中的不确定问题。针对典型的陆空复杂电磁环境仿真场景,计算频域、时域和空域等多维度指标,和电磁环境监测数据进行逼真度计算比对,分析计算重点战场区域的电磁环境实际构建效果,通过计算实例分析了逼真度评估的过程。

A macroscopic assessment method based on the fidelity of the electromagnetic environment was proposed. The electromagnetic environment fidelity assessment problem was transformed into the image similarity measurement problem based on Grey relational degree. The method effectively solves the uncertainty problem in the fidelity assessment process. For the typical land-and- space complex electromagnetic environment simulation scenario, multidimensional indicators such as frequency domain, time domain, and spatial parameters are calculated, and the fidelity calculation were compared with the electromagnetic environment monitoring data. Then the actual construction effect of the electromagnetic environment in key battlefield areas was analyzed and calculated;Finally, the process of fidelity assessment was analyzed through calculation examples.
