Radio Fuse Electromagnetic Compatibility Testing Research

With a more complex electromagnetic environment of the battlefield space and the wider application of electrical device in radio fuze systems, radio fuze must be carried on electromagnetic compatibility (EMC) test. In this paper, radio fuze was carried on the radiated emission test, the radiated immunity test and the electrostatic discharge (ESD) immunity test, and analyzed whether to be able to guarantee its reliability when it was suffered the limit electromagnetic environment.Because GTEM cell has a lot of advantages, it was chose to carry on the radiated emission test and the radiated immunity test for radio fuze. In this paper, firstly, the main technical specification of GTEM 250 cell were analyzed and confirmed, and a software for field stress measurement that based on the HI-6005 was designed to confirm the TEM mode and field uniformity. Next, a method that carried on the radiated emission for radio fuze with GTEM 250 cell was introduced, and total radiated power and radiated field stress on an OATS of typical radio fuze 1 and 2 were calculated, and a method that carried on the radiated immunity for radio fuze with GTEM 250 cell was introduced. Finally, both of typical radio fuze 1 and 2 were carried on the radiated immunity and the ESD immunity test and analyzed their results, so obtained their radiated immunity rank and ESD immunity rank.
