[Abstract]:The flight altitude of aircraft in aeromagnetism is usually not a plane, and the influence of observation surface fluctuation can be eliminated by warping treatment. In the measurement of multi-parameters, such as the measured magnetic field and its triaxial gradient, the multi-parameter warping method of measuring magnetic field can be studied. In this paper, through the calculation of the model, the normal derivative of gradient transformation is used to distort and flatten by boundary element method, and good results are achieved, and the magnetic field gradient is fully used to reflect the change rate of magnetic field in all directions. An idea is given for the comprehensive use of magnetic field and its gradient for warping treatment. The principle of this method is clear and the program implementation is simple.
