Abstract

This paper describes the fine structure of electric field waveforms produced by lightning return strokes. The electric field measuring system consists of hemisphere antenna 30 cm in diameter, integrator and data acquisition device. Its frequency bandwidth is from 200 Hz to 1.56 MHz, and the sensitivity is 0.96 mV/V/m. Electric field signals are digitized every 200 ns with the resolution of 12-bit and the length of 5 kilowords, and those are registered by a personal computer. Also data are analyzed by means of the fast Fourier transform (FFT) method.
