FIELD: radio engineering, in particular, meteorology and civil aviation, for operative detection of regions of thunderstorm activity at distances up to 2000 km. SUBSTANCE: method involves reception of lightning discharge signal by means of radar station, detection of discharge source position using earth signal, and iterating correction of this value by means of compensation of expected diffraction delay of earth signal along trajectory from calculated source position to each reception point in each loop. EFFECT: increased precision for detection of position of lightning discharge. 2 dwg
