摘要

我们提出了一种估算高频雨衰减的新方法。虽然这种方法是基于米氏理论,但由于减少了计算次数,它比旧的方法快得多。换句话说,不是对所有液滴直径使用Mie理论,而是只对作为分布指标的平均值进行计算。最后,答案必须被一个因子修正。我们得到了合适的公式,并通过仿真证明了其结果与以往方法的适应性。

A new method for estimating rain attenuation at high frequencies
We propose a new method for estimating rain attenuation at high frequencies. Although this method is based on the Mie theory, it is much faster than older methods because of a reduction in the number of calculations. In other words, instead of using the Mie theory on all drop diameters, the calculation is performed on only the mean value as an indicator of distribution. At the end, the answer must be corrected by a factor. We obtain the proper formula and show, through simulation, the adaptation of its result with previous methods.
