In recent years, reverberation chamber testing technology has been rapidly developed. This paper focuses on the reverberation chamber test principle and the differences in electromagnetic compatibility (EMC) test methods between the reverberation chamber and the anechoic chamber in the automobile industry. It selects several different test samples, performs comparison verification in the reverberation chamber and the anechoic chamber respectively, and analyzes the feasibility, adequacy, and effectiveness of the reverberation chamber technology that can be promoted in the future.
