Abstract
This paper takes the time-domain aeromagnetic system as the research object and uses the finite element software COMSOL Multiphysics 6.0 to establish the three-dimensional system model. By comparing the COMSOL Multiphysics forward simulation solution with the one-dimensional numerical solution, it verifies that the COMSOL software meets the simulation accuracy requirements of the three-dimensional time-domain aeromagnetic method, and focuses on the analysis of the transient response at different flight altitudes is also analyzed. Based on the analysis of this paper, a set of aeromagnetic parameters with high detection capability is determined for engineering practice, and a test of the system is completed.
