FIELD: electricity.
SUBSTANCE: electromagnetic radiation receiver system includes a sensor for magnetic induction to generate signals that represent changes in the legislation adopted by the magnetic field source waveform to generate the reference waveform with the first frequency, calibration loop, an, at least temporarily, next to the sensor of magnetic induction to generate a response signal in the sensor calibration of magnetic induction, when applied to the calibration verification of wave forms a loop and processing system for the determination of calibration factor. Calibration coefficient includes transfer function and impulse response signal to be applied to signals from the sensor of magnetic induction. Processing system determines the calibration factor depending how the response of the calibration signal and the known sensitivity of magnetic induction in the second the frequency range in which the known sensitivity corresponds to the effective magnetic induction of sensor area. The second frequency range is below the first frequency range.
EFFECT: increased sensitivity.
