Abstract

Aiming at some key test positions of the installed shielding vehicle that do not meet the test distance, the paper analyzes the prominent problems that are difficult or impossible to measure during the shielding effectiveness test, and analyzes the factors that cause the problem. The hole-cavity coupling theory is used to establish the theoretical correction factor models of different frequency bands in the installed state are established, and the correctness of the proposed method is verified through theoretical calculations and actual case tests, and the theoretical correction factor of the installed state is used to correct the shielding effectiveness of the known empty vehicle, to obtain the application shielding performance of key positions where the installed shielding vehicle does not meet the test distance, avoiding the testing of the installed shielding vehicle, thus greatly improving the ability to obtain the shielding performance of the installed shielding vehicle.
