Abstract

With the development of aviation industry, High Intensity Radiation Field (HIRF) has more and more influence on airborne electronic equipment. Therefore, it is of great significance to test and optimize the shielding effectiveness of airborne electronic equipment. In this paper, the test environment of HIRF was established based on RTCA/DO-160G and GJB 5185-2003. The shielding effectiveness of airborne electronic equipment is tested under the electromagnetic environment, and the effects of different test positions and different incident surfaces on the shielding effectiveness were analyzed. The main coupling channel of airborne communication equipment is obtained. Finally, a general optimization method for different coupling channels is proposed. The results can provide references for the test of airborne electronic equipment HIRF and the optimization of shielding body.

Key words： airborne electronic equipment; high-intensity radiated fields; shield effectiveness; electromagnetic coupling; shield optimization
