通过分析典型短波电台带内辐照试验,提出改变辐照试验电磁能量耦合途径以简化试验装置的设想。通过理论分析和仿真计算,分析了短波电台带内辐照试验的电磁能量耦合途径,得出电台天线是短波电台带内辐照试验主要能量耦合途径的结论,通过设计电磁辐照法和电流注入法比较试验,验证了仿真计算结论,且证明在该试验条件下电流注入法可以替代电磁辐照法。该结论可以推广到电磁能量耦合途径单一的电磁辐照试验中。
Based on the analysis of typical in-band irradiation experiments in shortwave radios, the idea of changing the electromagnetic energy coupling of irradiation experiments to simplify the experimental device was proposed. Through theoretical analysis and simulation calculation, the electromagnetic energy coupling of short-wave radio in-band irradiation experiment is analyzed, and the conclusion is drawn that the radio antenna is the main energy coupling way in the in-band irradiation test of shortwave radio station. Through the design of electromagnetic radiation and current injection Method comparison test, the simulation results are verified, and it is proved that the current injection method can replace the electromagnetic irradiation method under the test conditions. This conclusion can be generalized to the single electromagnetic radiation experiment of electromagnetic energy coupling.
