NOISE SUPPRESSION IN LOW-FREQUENCY CONTROLLED SOURCE ELECTROPROSPECTING. EXAMPLE OF APPLICATION FOR ORE DEPOSITS IN THE MAGADAN REGION
Abstract
In this paper, we present robust scheme of controlled source electromagnetic data
processing. We specify various types of noise that affect measurements and show how
these noise components can be suppressed. We promote an improved algorithm to process
noisy data. We demonstrate that our method can recover response functions from extremely
noisy field data. The proposed software can be adapted to new data sets and noisy
environments. We apply our processing method to field data from Komi, Norilsk region,
Pechora province and other areas in Russia. In this article we present processing data results,
obtained at Magadan region in 2009.
