| Abstract: | The paper describes a method of harmonics measurement based on DFT, analyses characteristic of different window function and its influence on harmonics testing, and Blackman window is used to increase measurement precision. According to the method, simulation and contrastive testing experiment based on military equipment are done, and finally, the error analysis of simulation and experiment are discussed, and cause of error is pointed out. |
