The exciting signal of time domain is transformed in FFT and the characteristics of system in frequency domain are analyzed. According to the results of simulation,a measurement district can be confirmed in which the electrical field is uniform. Methods of measurement are researched with the measurement signal of probe integrated by integrator and software respectively. The repetitive experiment and the linear experiment on D-dot probe and photoelectricity probe are conducted using the proposed system. The experimental result shows that the repeatability of calibration system is better than 2.8% ,therefore the calibration problem of EMP probes can be solved effectively %K 电磁脉冲 %K 探头 %K 校准< %K br> %K electromagnetic pulse %K probe %K calibration %U http://journals.tju.edu.cn/zrb/oa/darticle.aspx?type=view&id=201611010
