Abstract :
Introduces a pulse magnetic field measurement system which is used in strong electromagnetic environment. A small loop antenna is used as pulse magnetic field sensor and a wide band analog fiber transmission device is used to transmit the signal. The system uses BP neural network to calibrate the nonlinearity of the fiber transmission device and uses the model of the antenna to recover the pulse magnetic field. Using Matlab function to realize the system method can simplify the program. An experiment result shows that the system is suitable for measuring wide band pulse magnetic field.
