Discussion about the System Electromagnetic Pulse Effect Diagnostic Test

Objective To study the electromagnetic pulse effect of armament systems. Methods A method combining system theory calculation and components diagnostic test was used, and the electromagnetic pulse near field irradiation test and current injection test were carried out with the signal processing module of an equipment as the test object. By changing the test parameters such as field strength and injection current, the electromagnetic effect of electromagnetic pulse on the module was discussed. Results The test data on the electromagnetic pulse interference effect of the module were obtained under working conditions. The module would be sensitive when the irradiation field strength was 310 V/m or the cable coupling current was 4.3 A to 6.4 A, and multiple tests indicated that the completely sensitive threshold value would be a little higher. Conclusion Experiments proved that it was feasible to use the near field irradiation test and current injection test to develop electromagnetic pulse diagnostic test for the components, which is valuable for further study in electromagnetic pulse effect of more system modules.
