Abstract: Conjugate element inversion method of magnetic anomaly was studied. The method used magnetic anomaly
conjugate element to build conjugate triangle, through the conjugate points fitting realized inverse interpretation of
magnetic anomaly. This method solves part of geometrical element of magnetic source body at first, and then combining
the characteristics of magnetic anomaly plane, via calibration explanation, giving anomalous body’s other geometrical
parameters, such as the trend length, the extension depth, the angle of inclination, etc, and the magnetic field parameters.
This method has good antijamming ability. Furthermore, it has the good solution speed and the inversion precision
according to model experiment and example check result.
Key words: conjugate
