摘要
针对目前实验室条件下高强度辐射场无法构建,单一辐照法难以有效开展系统级电磁辐射敏感度及安全裕度试验的问题,对互联系统注入法等效替代电磁辐照法的试验技术进行了研究.以设备端口的响应电压相等作为等效依据,推导了注入电压与辐照场强之间的等效对应关系,确定了强场条件下注入电压源线性外推应满足的条件,提出了基于耦合模块的等效注入试验新方法.在理论分析的基础上,以典型非线性互联系统为受试对象,分别开展了单频连续波辐照与注入试验研究,结果表明:辐照场强和等效注入电压源之间为线性变化关系,替代高场强辐照试验的等效注入电压源可以采用低场强下的对应关系线性外推得到,试验结果验证了注入等效替代辐照试验方法的有效性.
High intensity radiated field （HIRF） cannot be simulated under the con- dition of laboratory presently, so it is hard to carry out electromagnetic radiated susceptibility and safety margin test for system with single radiation method. In or- der to solve the problems, the testing technology of using injection as a substitute for electromagnetic radiation is explored. The equal response voltage on the equip- ment cable port is regarded as equivalent principle. The equivalent correspondent relation between injection voltage and radiated field is put forward theoretical- ly. The conditions used to extrapolate injection voltage in HIRF are determined. The equivalent injection new method based on coupling module is proposed. On the basis of theoretical analysis, the typical nonlinear interconnected system is selected as e- quipment under test, and the single frequency continuous wave radiation and injec- tion effect experiments are carried out separately. The test results indicate that the relation between radiated field and injection voltage is linear, and the equivalent in- jection voltage used to substitute HIRF test can be obtained by linearly extrapola-ting the correspondent relation in lower radiated field. Furthermore, the test re- sults also verify the validity of the test method proposed in this paper.
