| Objective Based on the adaptability test requirement of radar pulse transient interference environment for ground platform system, a moveable intensive electromagnetic pulse interference simulation test system is studied. Methods System basic composition is studied, and the three key indicators affecting test system including test distance, transmit power and antenna gain are simulated and optimal designed. Results The output power of pulse amplifiers are all above 300kW. The field strength of test system is above 5000V/m at 5m distance, 2500V/m at 10m distance. Meanwhile the test system can meet the use requirements of movability and radiation area. Conclusion The signal form, output power of amplifier, VSWR, system match indicators of the test system are fully considered to ensure field strength distribution and radiation area. The technical parameters of the test system and the test conditions including implementation steps are accurately defined, and then the consistency and repeatability of test are greatly improved. At the same time, the test system can also be used in electromagnetic radiation hazard test of the ordnance system (EMRADHAZ). |
