Research on Error Analysis and Correction of LEMP Magnetic Field Measurement Device
According to the existing non-orthogonal error of lighming electromagnetic pulse (LEMP) magnetic field measurement device, the paper derives theoretical and actual output voltage of antennas induced by the alternating magnetic flux, which are generated by the current-carrying loop antenna injected with sine wave, gets the orthogonal extent and corrects the non-orthogonality of the device through simulation and calculation.In accordance with the existing low frequency distortion phenomenon of measured waveform, the paper uses output error (OE) system identification model to correct the error.The methods mentioned in this paper prove to be stable and efficient.It improves the accuracy of LEMP magnetic field measurement.
