Improving the Accuracy of Thunderstorm Clouds Detection in Mechatronic Systems for Remote Monitoring of Natural Hazards

At the heart of mechatronic systems for remote monitoring of natural hazards such as thunderstorms and hail clouds are radar research methods. A radar model of hail clouds is developed, taking into account the influence of the charge of individual hydrometeors on their scattering properties. Calculations have shown that within the framework of the considered radar model of a hail cloud, there is a noticeable increase in radar reflectance compared to a neutral cloud. At certain ratios between the average cubic diameter of the hail particles, the surface charge density and the wavelength, large bursts of radar reflectance occur. Such resonance phenomena are more pronounced in media with low absorption, which include ice.
