摘要

用于远程监测自然灾害(如雷暴和冰雹云)的机电系统的核心是雷达研究方法。考虑单个水成物的电荷对其散射特性的影响，建立了冰雹云的雷达模型。计算表明，在考虑冰雹云的雷达模式框架内，与中性云相比，雷达反射率明显增加。在冰雹粒子的平均立方直径、表面电荷密度和波长之间的一定比例下，雷达反射率就会出现大爆发。这种共振现象在包括冰在内的低吸收介质中更为明显。

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.
