Design of electromagnetic shielding for electro-optic reconnaissance platform

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.
