Abstract

In order to expand the dynamic measuring range of flux gate and improve the measurement accuracy and the work stability of flux gate, a flux gate signal processing method based on DSP digital signal processor was proposed. According to the basic principle of double iron core flux door, the analog to digital conversion of flux gate induction signal, digital waveform "gate" processing and digital bandpass filtering and other digital signal processing were carried out. The simulation results show that the flux gate signal processing method can effectively reduce the flux gate noise, improve the flux gate sensitivity and measurement accuracy, and also provide a reference for the application of digital flux gate magnetometer.

Key words： flux gate; digital signal processing; digital signal waveform "gate" processing; digital bandpass filtering
