Typical Radio Fuse Electromagnetic Compatibility Testing And Analysis

With the rapid development and wide application of electronic and electrical appliance technology on computer, information technique, test equipment, semiconductor, more and more electronic equipments are used on the battlefield. Radio fuze is interfered badly because of a more complex electromagnetic environment of the battlefield space. To make sure radio fuse work very well, it's electromagnetic compatibility must be studied.The paper researches two kinds of typical radio fuzes. Base on the equipment and Graphics language-LabVIEW, the compatibility of the radio fuses are studied in different electromagnetic environment by testing their radiated immunity.A data acquisition system is designed in the paper. It is finished with ADLINK DAQ-2206 data acquisition card based on the LabVIEW software platform and some relative hardware. This system has some important function such as multichannel continuous data acquisition, parameter settings, waveform display and so on. It meets the testing requirements. GTEM250 cell is used to test radio fuze radiated immunity. In the paper, Firstly main properties and technical specification of GTEM cell is introduced. Secondly, according to IEC61000-4-20 field uniformity is calibrated, and then radiated immunity of two kinds of typical radio fuzes are tested and their output signals are acquired Finally, typical radio fuzes are analysed with collected data and theoretical knowledge, and their compatibility in different electromagnetic environment are concluded.
