Methodology of time-domain & frequency-domain calibration and equivalence for EMP sensor
Xie Yan-zhao, Liu Shunkun · Hedianzixue yu tance jishu · 2004
In order to measure the waveform and amplitude of EMP accurately, the sensors need to be calibrated under the standard fields in the TEM or GTEM cell. A set of calibration system is discussed in this paper. A highly accurate method of calibrating such sensors is applicable to techniques in both the frequency domain and in the time domain. The complete frequency-domain transfer function or the time-domain impulse response function of sensor system can be obtained, thus allowing deconvolution processes to be used to remove perturbations from the measurement waveform by the instrumentation and TEM cell.
