Interference Effects Study of Aircraft on the Earth's Electromagnetic Response Basing on Airborne VLF and LF Data

Very Low Frequency (VLF) electromagnetics (EM) has been widely and successfully applied in mineral exploration and ground water exploration in the past decades.Basing on the experiences from ground measurements with the Radio Magnetotelluric (RMT) technique operating in the frequency interval 1-250 kHz, the multifrequency magnetometers has been utilized to cover both the VLF (10 -30 kHz) and LongWave (LF, 30-300 kHz) bands to increase the resolution of the earth. The metallic aircraft which is a very conductive body could disturbed the magnetic signal and thus the investigation of the interference of the aircraft on the electromagnetic signal is becoming more important.
