| 摘 要： | 为了使光电侦察平台满足现代战场复杂的电磁环境要求，对某型光电侦察平台进行了电磁屏蔽设计。电磁屏蔽技术是抑制辐射干扰、提高系统电磁兼容性的最有效手段之一。分析了光电侦察平台在进行电磁屏蔽时的技术难点，根据其特有的技术难点，提出了一些实际可行的解决措施。对改进后的光电侦察平台进行了电场辐射发射（RE102）试验测试。测试结果表明经过合理的电磁屏蔽处理，可使光电侦察平台电场辐射发射值降低约10 dBV/m，提高了光电侦察平台的电磁兼容性。综合采取屏蔽、接地及滤波等技术手段，可使光电侦察平台的电磁兼容性满足GJB151A-1997中的规定。

| Abstract: | In order to satisfy complicated electromagnetic environment, electromagnetic shielding for electro-optic reconnaissance platform was designed specially. Shielding is one of the most effective methods for inhibiting radicalization interference and improving electromagnetic compatibility(EMC) of the system. Shielding difficult points of electro-optics reconnaissance platform was analyzed in detail, and the resultful measures were taken to solve the problem of radicalization interference for electro-optics reconnaissance platform. Radiated emission(RE102) tests were made to prove the effects of the improved reconnaissance electro-optics platform. Test results show that the degree of RE102 can be reduced about 10 dBV/m, and the EMC of electro-optics reconnaissance platform is improved. Through the combination of analyses and calculations by shielding, grounding and filtering, the EMC of electro-optics reconnaissance platform can satisfy the requirements of standard GJB 151A-1997. |
