PROCESS OF LOCATION OF ANOMALOUS ZONES OF THE EARTH'S FIELD Russian patent published in 1998 - IPC

FIELD: geophysics, search for mineral resources, applied medicine for detection of positions of zones unfavorable for biological objects. SUBSTANCE: process includes measurement of intensity of electromagnetic field, summing of amplitudes in frequency range and formation of intensity chart in horizontal plane. If summary intensity exceeds 100 mV/m anomalous zone has extent for all values greater than 100 mV/m and if summary intensity is less than 100 mV/m maximum value of intensity of local maximum is added together with minimum value of intensity measured between local maxima adjacent to it and average intensity is computed. If value of intensity of local maximum is 40% higher than computed average value of intensity then extent of anomalous zone for such local maximum is located at values from this average intensity to intensity of local maximum. EFFECT: expanded application field, increased functional reliability. 11 dwg
