    Abstract

  • The induction magnetometer is an instrument for detecting AC magnetic field from 10Hz to 20kHz in space. The probes are three-axis orthogonal coordinated. Because of the uniqueness and diversity, there is no general ground testing software for specified satellite platforms or payloads at present. In order to test in detail before launch, a data preprocessing software system based on Matlab is designed for induction magnetometer. The software system integrates waveform, amplitude and phase display interfaces. Meanwhile, plenty of data processing functions are designed for the characteristics of wide frequency band and three-axis orthogonal, such as multi-resolution fast Fourier transform, moving average filtering, phase difference calculation. Experiments prove that it can meet the requirements of all-directional load testing and verification.
