Research progress of the time-domain airborne electromagnetic method

We present the development history and current status of the time-domain airborne electromagnetic method, including the instrument system, data processing, forward modeling and inversion algorithms and application cases in China and elsewhere in the world. We suggest the following targets for the efforts of this technology in our country: (1)A perfect instrument system, which can suppress noise and acquire more useful information. (2) Efficient methods of data processing, which can facilitate finding small anomaly bodies in the subsurface. (3) Robust algorithms for forward modeling and inversion suitable for airborne electromagnetic data. And (4) fine interpretation methods which combine multiple data from real exploration work as well as existing techniques in this aspect to attain higher accuracy.
