Testing And Researching On Electromagnetic Shielding Of Military Electromagnetic Shielding Shelter

As the motor-vehicle operating environment,Shelter shielding military-style command system must have electromagnetic shielding properites,and the Shelter Test to the military-style system is the best testing means to electromagnetic shielding design and production technology.A strange guarantee for the applicability of the accuracy of the results.we also explored how to achieve normal value in nonstandard environment,for example,sometimes the cabin space has changed so that meet the standard test conditions.Through research and simulation,we presented shielding of electromagnetic shielding Shelter Performance testing and evaluation methods in the cabinet of the case.and applied to the project through the practical test to verify the correctness and feasibility.Firstly, we approached the base of the military shelter electromagnetic shielding principle and the test standrad;then introduced some basic theory,the dynamic range of the electromagnetic shielding test.Through the analysis of factors which affect the dynamic range,we developed the basic ways and means to improve the test system,and this will provide.Shelter on military-shielding the electromagnetic shielding effectiveness tests can be divided into diagnostic testing and compliance testing.Diagnostic test is to identify where and why the leakage take place,to take timely corrective measures to improve and enhance the electromagnetic shielding effectiveness;standard test is based on the electromagnetic shielding effectiveness of the corresponding standards and specification methods to test,Assess whether the standard requirements.The testing methods of improving the dynamic range of the electromagnetic shielding effectiveness suitable for the entire cabinet space under the condition of the electromagnetic shielding effectiveness of the testing and evaluation methods have been applied to a large number of actual test, and achieved good results.
