Research on an Optimized Recording Method of Actual Electromagnetic Environment Signal

Recording of the actual electromagnetic environment signal is a prerequisite for testing the vehicle performance in the electromagnetic environment in the chamber. Based on the research of the existing electromagnetic environment recording scheme, the influence of the coupling current of the RF cable shielding layer on the test results is analyzed, and an electromagnetic environment signal recording method on the basis of the optical fiber link system is proposed. It is verified that this method can effectively reduce the influence of the shielding current of RF cable and improve the accuracy of the test results.
