Complicated battlefield electromagnetic environment seriously affects the safety, reliability and technical index of airborne electro-optical platform. Electromagnetic shielding of minitype airborne electro-optical platform was designed in order to improve its battle efficiency. Firstly, the shielding effectiveness of electromagnetic shielding was expounded. Design of electromagnetic shielding was carried out for minitype airborne electro-optical platform from the aspects of circuit board, ABS shell, gaps and video transmission. The shielding effects were verified by electromagnetic compatibility test. The test results show that the video image is normal, conduction emission value is reduced by about 20 dBV, radiation emission value was reduced by about 10 dBV/m, and other items test are improved to varying degrees, which provide a reference for the design of electromagnetic compatibility for minitype airborne electro-optical platform.
