FIELD: instrument making.
SUBSTANCE: invention relates to sea bottom sounding data processing. The proposed method comprises generating electromagnetic radiation for electromagnetic field components to be measured by the receiver. Note here that the radiation source is located close by the receiver so that the incident signal dominates over ascending signal reflected from geologic horizon above the receiver. Such measurements can be used in analysing in frequency bands to isolate the signal incident component and to design the receiver calibration filter. In subsequent processing, electromagnetic data incident component is removed. The proposed method is repeated for each receiver used in electromagnetic sounding.
EFFECT: new method and device for producing electromagnetic data calibration filter.
