屏蔽网遮挡电磁干扰效果评估研究

摘要

Combining computer simulation experiment technique with solid equipments countermeas-ure experiment technique the effect evaluation of low elevation electromagnetism interference shelter in Shielding net is researched. Firstly, Mathematic diffraction formula is deduced, and a mathematic model is built and computer simulation experiment is carried out. Secondly, the effect of low elevation electro-magnetism interference shelter in Shielding net based on solid equipments countermeasure experiment is evaluated. By comparison and analysis for the result data of the simulation experiment and the solid e-quipment countermeasure experiment, the result is consistent with the latter, thus the evaluating method is proved scientific and feasible. The effect evaluation of low elevation electromagnetism interference occlusion in shielding net is also obtained.%采用计算机仿真实验和实装对抗试验相结合的方法,完成了屏蔽网遮挡低仰角电磁干扰效果的评估.首先推导了绕射数学公式,建立了数学模型,并进行了计算机仿真实验.通过实装对抗试验检验了屏蔽网遮挡低仰角电磁干扰效果,通过比对分析仿真结果和实装对抗试验数据,结果基本一致,证明了采用的评估方法科学可行,给出了屏蔽网遮挡低仰角电磁干扰的效果.
