| 摘 要： | 在瑞利散射、液态水介电常数模型、雾滴谱分布基础上,分析了单个云雾粒子和群雾滴的电磁传输特性.数值模拟计算表明,电长度是影响云雾粒子电磁传输特性的主要因素,温度的影响相对较小.平流雾分布的电磁传输特性强于辐射雾的传输特性,影响群雾滴传输特性的因素由大到小依次为人射波频率、含水量和温度.所得结论对提高降水测量的精度,减小卫...

| Abstract: | Based on the Rayleigh scattering theory,the model of specific inductive capacity of liquid water,and fogdrop size distribution,the transmission characteristics of individual cloud and fogdrop particles and fogdrop cluster are analyzed.The results show that the electrical length is the main factor that affects the electromagnetic transmission characteristics of clouds and fogdrops.The transmission characteristics of advection fog size distribution are stronger than those of radiation fog size distribution.Th... |
