REMOTE FREQUENCY SOUNDING METHOD Russian patent published in 1997 - IPC

FIELD: geoelectric prospecting. SUBSTANCE: variable magnetic field is excited by vertical magnetic dipole, ratios H_a/H_b of large and small axes of polarization ellipse are measured at number of frequencies, distance between excitation points and observation points for which H_a/H_b ratio equals constant value C at each operating frequency is measured, and electromagnetic parameter of field P is found from measured distances (r_i), frequency (f_i), and constant C; electromagnetic parameter and plant parameters (r_i, f_i) are used to determine geoelectric section of area under study. EFFECT: facilitated sounding procedure. 3 dwg
