Research performance frequency-modulated signals in anisotropic environment with the aid of matlab software

Abstract

Relevance of consideration in this paper tasks is to improve the existing methods of electromagnetic geological exploration and development of new methods of search and identification of oil and gas fields on the basis of frequency modulated (FM) signals. Using the software Matlab analyzes the frequency components of the surface impedance of the medium over hydrocarbon deposits (HD) when changing the FM, a variation of which extends the functionality of the components depending on the resistance of the modulation modes and to improve the information content of the developed methods to search for HD. In this paper we have determined values of the components of the surface impedance of an anisotropic medium plasma-type, which was selected as the hydrocarbon deposit. The propagation of electromagnetic wave pools in FM mode signals. The analysis is conducted in the impedance-frequency range of sounding signals. Various modes of application FM modulation. The results of interaction of FM signals with the environment over HD can be used for the development of radio-engineering signals (RES) search of oil and gas and improve the performance of high-quality exploration.
