Estimation of electromagnetic parameter of stratum based on Kriging interpolation

The distribution of electromagnetic parameter in stratum is a basis of the design of the through-the-earth communication system and selecting of the equipments' electrical parameters. Because there is great difference of electromagnetic parameter between different geological strata, a great bias will be brought out during the research of the electromagnetic propagation characteristics of the through-the-earth communication based on the simplified stratum media model. In order to solve this problem, Kriging interpolation algorithm is originally adopted to setup a stratified stratum media model and estimate the distribution of the electromagnetic parameters in the mutant stratum media. By this interpolation method, the high precise electromagnetic parameters and stratum media model can be provided for the design of communication system and the numerical calculation of electromagnetic propagation.
