Phase method with accumulation of electrical signals and GPS-synchronization
Under consideration is the phase method with accumulation of electrical signals and synchronization by signals from GPS-receivers, in which the main informative parameter is the angle between the primary magnetic field excitation and the measured magnetic field in the area of study. Excitement of rocks are done by rectangular pulses with current loop, and the signal which is perceived broadband magnetic field sensor is analyzed on the main excitation frequency and on the number of odd harmonics. The method is designed to detect and locate anomalies in the electromagnetic field of ore deposits. Its high resolution is shown on the example of the test of the method on a known chalcopyrite field.
