Summary: | Aeromagnetic detcetion is a popular technique for finding of hidden or buried ferromagnetic objects. But the magnetic interference generated by the aeromagnetic platform constitutes a troublesome issue. To compensate the interference, the Tolley-Lawson (T-L) model is widely used. However, subject to the applicable conditions, the compensation effect is not always satisfactory. In the paper, a modified T-L model is proposed, in which the compensation coefficients are taken to be relevant to the heading angle of the aircraft. As a result, the original 18-term T-L model are extended to 54 terms to betterly eliminate the interference. Simulated site experiment results show that the modified model can separate out more interference and provide much better compsenseted data. |
