摘要:

针对现有差模注入等效试验方法局限性导致的误差, 基于电磁场理论分析了误差产生原因, 提出了天线耦合途径下的校正方法, 实现了注入试验结果与测试标准要求的电磁辐射试验结果等效。以复杂电磁环境下易出现干扰损伤效应的用频装备为研究对象, 将通信电台这一典型用频装备作为受试设备, 开展了带内和带外阻塞效应强场电磁辐射等效注入试验, 提出了工作信号和干扰信号同时存在的校正方法并进行试验验证。结果表明, 接收天线为主要耦合途径下, 差模注入法等效电磁辐射法的精度高, 等效注入试验所需电磁功率显著小于辐射试验。

Abstract:

Aiming at the error caused by the limitation of the existing differential-mode injection equivalent test method, the reason for the error is analyzed based on the electromagnetic field theory. The correction method with the antenna as the coupling route is proposed. The equivalence between the injection test result and the radiation test result required by the test standard is realized. The spectrum-dependent equipment which is prone to interference damage effects in a complex electromagnetic environment is used as the research object. The communication radio is used as the equipment under test (EUT). The in-band and out-of-band blocking effects strong field electromagnetic radiation equivalent injection test is carried out. A correction method for the simultaneous existence of working signals and interference signals is proposed and verified by experiment. The results show that the equivalent electromagnetic radiation method of the differential mode injection method has a high accuracy, with the receiving antenna as the main coupling route. The electromagnetic power required by the equivalent injection test is significantly less than that of the radiation test.

Key words: spectrum-dependent equipment, high intensity radiated field, current injection, electromagnetic environment effect
