Abstract

Each year there is a great volume of airborne electromagnetics in Russia, estimated hundred thousand linear kilometers. Among the equipment involved in this survey, the greatest share is occupied by system, developed by «Geotechnologies» JS. Changing position between receiver and transmitter leads  to changing of induced field parameters in receiver axes by value much higher than amplitude of the useful signal. Until recently, due to this circumstance, it was impossible to use inphase component of the response in data interpretation. Institute of Control Sciences together with «Geotechnologies» JS has developed algorithms that allow to detemine relative positioning of the receiver axes with respect to inducing moment vector. It has allowed passing without accuracy loss from polarization ellipse invariants to components of the reflected field. Their usage led to a new quality level of interpretation.
