Reconstruction research of matrix pencil method about airborne electromagnetic response data

There is a changing trend of attenuation exponential summation on a huge volume of electromagnetic response data in the research of time-domain airborne electromagnetic exploration. According to this changing trait, in this paper, matrix pencil method is used to extract characteristic parameters like pole from the electromagnetic response data, as well as to complete descending rank and reconstruction of the electromagnetic response data. Algorithm analysis and example result prove that, either non-noise environment or including noise environment, matrix pencil method realizes better approximating precision between original curve and reconstruction curve, and guarantees a lower precision wave with large extent of signal-to-noise ratio variation. Therefore, this algorithm possesses excellent resisting noise disturbance capacity and stability, and is an efficient mathematics tool to rapidly explain airborne electromagnetic response data in complex electromagnetic environment.
