Description
Summary:The influence of the parameters of sensors and receiving and transmitting devices with dielectric shells on the spectral characteristics of signals induced by an artificial thunderstorm cell (ATC) has been experimentally investigated. Based on wavelet analysis of the signals induced by the ATC, differences in spectral characteristics compared with rod electrodes were established. Four systems of electrodes with dielectric caps are considered, and characteristic spectral ranges corresponding to the formation of flashes of positive streamer corona and negative reverse discharges from the model electrode are determined. It is established that, with an increase in the radius of curvature of the working elements of sensors and antenna devices, higher characteristic frequencies can be expected in the spectrum of current pulses of the streamer corona and negative reverse discharge. It is noted that the characteristic frequency ranges found in the spectra of the current pulse of the positive streamer corona and negative reverse discharge may be present in signals induced in thunderstorm conditions on sensors and receiving–transmitting devices having flat and extended working elements, which can cause false alarms and malfunctions of sensors, analog-to-digital converters and information-transmission devices.
