摘　　要：频域测试在测量列车电磁场时需要较长时间,而时域测试具有测试速度快、效率高的优点。采用自行研制的超宽带天线和环天线,分别对列车内部电场和磁场进行时域和频域测试。将时域测试数据转换到频域,与直接频域测试数据对比,验证了频转换方法及时域测试结果的有效性。Comparing with time-domain test, frequency-domain test costs a lot of time. A self-developed uhra-wideband electric field antenna and an ordinary loop antenna are adopted in electric field and magnetic field tests, for both time and frequency domains. By using the method of time-frequency conversion, the test data in time domain are transformed into the f^quency-domain data. The comparison is made between transformed data and direct test data in frequency domain. The result shows the validity of timefrequency transforming method.
